(d) At all approved events, the licensee may exercise only those privileges authorized by the licensee’s license and shall comply with all provisions of the act pertaining to the conduct of on-sale premises and violation of those provisions may be grounds for suspension or revocation of the licensee’s license or permit, or both, as though the violation occurred on the licensed premises.
(e) The fee for a caterer’s permit for a licensee under an on-sale general license, a caterer’s permit for a licensee under an on-sale beer and wine license, or an event permit for a licensee under an on-sale general license or an on-sale beer and wine license shall be the annual fee as specified in subdivision (b) of Section 23320, and the fee for a caterer’s permit for a licensee under a club license or a veterans’ club license shall be as specified in Section 23320, and the permit may be renewable annually at the same time as the licensee’s license. A caterer’s or event permit shall be transferable as a part of the license.
(f) A catering authorization shall not be issued for use at any one premises for more than 36 events in one calendar year, except when the department determines additional events may be catered to satisfy substantial public demand.
