In Ballesteros v. Alcoholic Bev. etc. Appeals Board (1965) 234 Cal. App. 2d 694, an underage woman entered a bar with her husband and a group of friends, all over 21. The bar was dark and busy. The minor and her friends sat at a table at the opposite end of the room from the bar where the lone bartender was working. The minor's husband and two of her friends went to the bar to order drinks, including a soft drink for the minor. Because the bartender was familiar with the minor's husband and some members of the group the minor accompanied, having checked their identifications on prior occasions and determined they were of age, he served the requested drinks. The bartender did not approach the party's table or otherwise notice the minor's presence. "A few minutes" later, a police officer entered the bar, approached the minor's table, and determined that she was not yet 21. According to the minor, she had been in the bar for 10 minutes before the officer arrived. ( Id. at pp. 696-699.) Based on those facts, the Ballesteros court found the bartender had been "inactive or passive" with respect to his duty to ascertain the minor's age, and so had, in effect, permitted the minor to remain on the premises for "at least ten minutes." ( Ballesteros, 234 Cal. App. 3d at pp. 700-701.)
