Appellant was convicted of carrying a pistol without a license, 1 possession of an unregistered firearm, 2 and possession of unregistered ammunition. 3 On appeal he challenges only the trial court’s denial of his motion to suppress evidence. We find his challenges without merit and affirm the conviction.
*774 I
Shortly before sunrise on a Sunday morning in October 1982, at about 6:45 a.m., Officer Sal Lauro of the United States Park Police was patrolling near the Carter Barron Amphitheater in Rock Creek Park when he decided to make a routine check of the amphitheater’s parking lot. The lot is used by several bus companies to pick up and discharge passengers who take overnight trips, and as a result unattended automobiles are frequently left in the lot for extended periods of time. Officer Lau-ro knew that there had been recent larcenies from some of these parked cars, so he drove through the lot to make sure that “everything was okay.” There were about forty or fifty cars in the lot, and in one of them Officer Lauro discovered appellant seated in the right front seat. His eyes were closed, and his head was slumped to one side. He appeared to be either asleep or unconscious. The officer stopped his cruiser about ten feet away from the car in which appellant was sitting. By radio he checked its license number through the police computer to see if it had been reported stolen. He found that it had not been, but he also found that it was registered to a female owner.
Officer Lauro then got out of his cruiser and walked over to the car with a flashlight in his hand. He tapped on the window next to appellant to find out whether he might need some assistance. At the sound of the tapping appellant woke up. The officer asked him to roll down the window; when he did so, Lauro asked him for some identification and an explanation of what he was doing there. Appellant replied that he was waiting for his girl friend to return from a bus trip, but he failed to identify himself, so the officer asked him again for identification. Appellant began to rummage through his pockets and the glove compartment of the car while Officer Lauro waited for a response. As he stood there next to the car, the officer saw a package of cigarette papers and a brown manila envelope, of the sort “commonly used to package marijuana,” lying on the console between the two front seats. He asked appellant to hand him the envelope and the cigarette papers, and appellant passed them to the officer through the open window. Officer Lauro then asked him a third time for identification, and at the same time he opened the envelope, looked inside, and recognized its contents by sight and smell as marijuana.
After asking appellant a fourth time for identification, Officer Lauro spotted what appeared to be a “small telephone book” 4 in appellant’s back pocket when appellant leaned forward. Thinking that he was attempting to conceal his identity, Officer Lauro ordered him to get out of the car so that he could examine what was in his back pocket. Appellant stepped out of the car without his shoes on. As he leaned back into the car to get them, the officer shined his flashlight into the front seat area and saw what appeared to be the butt of a gun protruding from under the floor mat on the passenger’s side, where appellant had been sitting. Lauro grabbed appellant and took him to the rear of the car, where he patted him down for weapons but found none. He then went back to the open front door, reached into the car, lifted the floor mat, and found a .22 caliber automatic pistol loaded with six rounds of ammunition. Officer Lauro placed appellant under arrest, searched him, and found eight more rounds of ammunition for a .22 automatic in his pocket. Appellant then told the officer that he had the gun for protection because he had to wait in a dark parking lot for his girl friend.
Appellant moved to suppress the gun, the ammunition, and the statement. 5 The *775 trial court denied the motion on the ground that the officer had seen the gun in plain view when appellant got out of the car, and that the gun gave him probable cause to arrest appellant. We affirm the denial of the motion, but on different grounds. 6
II
Appellant’s principal contention is that Officer Lauro’s request for identification constituted a detention or seizure, and that it was unlawful because the officer had no articulable suspicion that appellant had committed or was about to commit a crime. The government argues, to the contrary, that the officer’s request was not a seizure, a detention, or even a stop. We think the government has the better argument.
This court has intimated on several occasions that a police officer’s request for identification does not invade rights protected by the Fourth Amendment.
E.g., Sanders v. United States,
The Supreme Court was confronted with this question in
United States v. Mendenhall,
Examples of circumstances that might indicate a seizure, even where the person did not attempt to leave, would be the threatening presence of several officers, the display of a weapon by an officer, some physical touching of the person of the citizen, or the use of language or tone of voice indicating that compliance with the officer’s request might be compelled.
Id. (citations omitted). Justice Stewart then concluded:
On the facts of this case, no “seizure” of the respondent occurred. The events took place in the public concourse. The agents wore no uniforms and displayed no weapons. They did not summon the respondent to their presence, but instead approached her and identified themselves as federal agents. They requested, but did not demand to see the respondent’s identification and ticket. Such conduct, without more, did not amount to an intrusion upon any constitutionally protected interest. The respondent was not seized simply by reason of the fact that the agents approached her, asked her if she would show them her ticket and identification, and posed to her a few questions.
*776 Nor was it enough to establish a seizure that the person asking the questions was a law enforcement official.... In short, nothing in the record suggests that the respondent had any objective reason to believe that she was not free to end the conversation in the concourse and proceed on her way, and for that reason we conclude that the agents’ initial approach to her was not a seizure.
Id.
at 555,
Although this view did not command the support of a majority of the Court, it was not rejected by a majority either.
7
Several courts since
Mendenhall
have found Justice Stewart’s reasoning persuasive, even though it is not binding precedent. In par-. ticular, courts have considered his list of “examples,” quoted above, in deciding whether a particular police-citizen encounter amounted to a seizure.
E.g., United States v. Sugrim,
Two cases, decided at almost the same time, illustrate how we have dealt with requests for identification by police officers. In
Crowder v. United States,
In this case, three policemen alighted from two squad cars near where Crow-der was standing, and one of the policemen demanded identification from him. This was a show of authority sufficient to restrain appellant’s liberty, and is consequently a “seizure” within the meaning of Terry [v. Ohio, supra ].
Id. at 1185.
Less than two months later, in
Harris v. United States,
With regard to the initial confrontation in the parking lot, we held that there had been no seizure:
It is clear that at least until the time of appellant’s entry into the police vehicle, the situation was totally lacking in any elements of duress other than those normally inherent in every street encounter between police and citizen. It was only upon appellant’s entry into the police vehicle with the preceding pat-down that any claim of duress could conceivably be made.
Id. at 1019 (emphasis in original). Read together, Harris and Crowder establish that we must look to all the circumstances of the encounter, not just the fact that there has been a request for identification, to determine whether there has been a Fourth Amendment violation. Indeed, it is clear from Harris that unless there is some element of duress in the encounter, either by. force or by a show of authority, a request for identification, without more, cannot be regarded as a seizure within the meaning of the Fourth Amendment. Accord, United States v. Castellanos, supra.
Guided by these precedents, we turn to the facts of this case. Officer Lauro found appellant, either asleep or unconscious, in a car in a parking lot at 6:45 on a Sunday morning. A check of police records showed that the car was registered to a woman, which appellant plainly was not. In these circumstances the officer “clearly had a right to investigate and inquire as to what the car and its occupant were doing there.”
Tyler v. United States,
*778 III
The trial court held that the seizure of the gun and bullets was lawful because Officer Lauro was standing next to the car, where he had a right to be, when he saw the gun butt in plain view. While this holding appears to be correct, it does not go far enough because the officer would not have seen the gun at all if appellant had not first gotten out of the car at the officer’s command. We must therefore determine whether Officer Lauro acted lawfully in ordering appellant out of the car.
See Jones v. United States,
The uncontradicted evidence
11
established that Officer Lauro, while he was waiting outside the car for appellant to find his identification, saw a small manila envelope and a package of cigarette papers lying next to each other on the console. The officer recognized the envelope as one that is “commonly used to package marijuana.”
12
We may assume that no single fact known to the officer at that point would have been sufficient to establish probable cause for an arrest or a seizure; indeed, we have held that the “mere existence” of such an envelope cannot create probable cause to believe that it contains narcotics “merely because it is frequently used for that purpose.”
Price v. United States,
Even though the envelope alone might not establish probable cause, the combination of the envelope and the cigarette papers, lying on the console only inches apart, made it reasonable for the officer to believe that the envelope contained marijuana. In addition, the officer had ample reason to believe that appellant, a man, was not the owner of the car, for the car was registered to a woman. Appellant’s evasive behavior was another factor which the officer could take into account: he had asked appellant twice to identify himself, but appellant had neither produced any identification nor explained his failure to do so. Finally, appellant’s lonely presence in the parking lot at 6:45 a.m. on a Sunday was an unusual circumstance in itself, made all the more suspicious by the fact— known to the officer — that there had been recent thefts from cars left overnight on this very lot. Viewing all of these circumstances in combination, as we must,
13
we hold that the officer had probable cause to believe that the envelope contained marijuana.
See, e.g., Thompson v. United States,
We therefore hold that the trial court committed no error in denying the motion to suppress.
Affirmed.

. We assume that the officer meant a pocket-sized address book rather than a telephone directory.
. Appellant was not charged with possession of marijuana, apparently because the amount of marijuana in the envelope was too small to meet prosecution guidelines.
. It is well settled that an appellate court may affirm a decision for reasons other than those given by the trial court.

Mendenhall
was a 5-4 decision. Justice Stewart’s opinion was for the most part the opinion of the Court, but on this particular point he wrote only for himself and one other justice. The other three justices in the majority concluded that the agents had a reasonable suspicion that the defendant was engaging in a criminal activity when they approached her, so that their questioning her in the airport was justified as an investigative stop under
Terry v. Ohio, supra.
These three justices therefore did not reach the issue of whether merely asking for identification in a public place invades Fourth Amendment rights, although they did "not necessarily disagree with the views expressed” by Justice Stewart on the subject.
