9 NYCRR 49.10

For licensees that choose to allow customers to bring their own alcoholic beverages on the licensed premises for consumption, lockers shall be provided by the licensee for the use of persons frequenting the licensed premises so that alcoholic beverages owned by each person may be securely kept under lock and key. Any alcoholic beverages not being actually used or consumed by the owner thereof shall be kept in a locker designated to the use of such person. A separate locker shall be assigned to each person applying for the same and the licensee shall not permit more than one person to use a single locker. All alcoholic beverages brought into the licensed premises shall be the personal property of the owner thereof and shall be consumed only by himself and his guests accompanying him. The locker assigned to each person shall be under the control of such person and alcoholic beverages may be removed therefrom only by the owner to whom the locker has been assigned or by an employee of the licensee at such times when the owner of the locker is in the licensed premises and requests such service.
