*261 OPINION
By the Court,
In this case Mrs. Asmussen (plaintiff-appellant) slipped and fell on a waxed linoleum floor. At the close of the case the trial court directed a verdict for the New Gоlden Hotel Company (defendant-respondent). NRCP 50 (a). The judge apparently beliеved that a finding of liability was precluded as a matter of law. We agree, and affirm thе judgment.
The facts are undisputed. On January 13, 1962 Mrs. Asmussen, an invited guest of the hotel, stepped frоm the elevator onto the hotel lobby floor. Her right foot slipped from under her. Shе fell to the floor and was injured. While on the floor she saw that the linoleum “was very heavily waxed, the wax lying on top rather than being buffed in.” No wax rubbed off on her clothes. About а yard away was a mark approximately a foot and a half long and an inch and a half wide, where the wax had been disturbed. She does not claim to have caused that mark. She did not notice the heavily waxed floor before she fell. Such is the story of the occurrence as related by her. No other evidence was offerеd on the issue of liability. The defendant chose to rest without introducing any evidence. Thе record does not show who waxed the floor, what materials were used, when the wаxing was done, nor the manner or method used in applying it to the floor surface.

Of course a proprietor owes his invited guests a duty to keep the premises in a reasonably safe condition for use — the duty of ordinary care. The experience of mankind demands that the illusory standard of ordinary care be applied in a reаsonable fashion, and courts generally have done so. Thus we perceive а clear distinction in the law between a “slip and fall” caused by litter, debris, (Wagon Wheel v. Mavrogan,
Here, as in Bonawitt, the record does not shоw the material used nor the manner of its application. We are asked to infer a basis for liability from the mere observation of the plaintiff that the floor was heavily waxed and not buffed in. It would be manifestly wrong to allow a jury to infer that an improper wax was used when the record is silent on the point. For the same reason the

fact finder should not be permitted to speculate that the wax used should have been buffed, rubbеd or polished. We do not know whether buffing, rubbing or polishing increases slipperiness, or lessens it; whether it is for beautification or safety. Nor would jurors be expected to have such knowledge. We therefore conclude that it is impermissible to infer that an unbuffеd waxed floor is dangerously slippery. To do so would effectively destroy the requirement that a claimant show either that the proprietor was negligent in the materiаl used or in the manner of applying it. The following cases support our view: Barnes v. Hotel O. Henry Corporation,
Affirmed.
