"I need a link to the ordinance that states it is illegal for a minor to sell alcohol."
=========================================
My response:
Q. 80. May an off-sale* licensee hire minors or use the services of a person under 18 years of age for the sale of alcoholic beverages?
A. Yes, if the person under 18 years of age is under the continuous supervision of a person 21 years of age or older. (Business & Professions Code section 25663)
* "Off-Sale" means any establishment; e.g., a liquor store, where alcoholic beverages are sold, and taken out of the store for consumption - - as opposed to a restaurant where alcoholic beverages are meant to be consumed on-premises.
