ask yourself why is food sold after ticketing, rather than before?
At most theaters in Los Angeles, you can go to the concession stand without buying a ticket, and some theaters such as the Arclight actually have nice restaurants and wine bars that cater to people who aren't going to movies at all. That said, I'm not sure who would pay $6 for popcorn and $5 for a soda when not forced to because that is the only option allowed in the theater.
It is the same with beer. You can get beer for $0.50-$1 per bottle at a grocery store, but it is $3-$5 at most bars. Even if California law allowed it, I wouldn't go into a bar for a $5 beer and then take it home. I would only drink the $5 beer in the bar because that is the only option allowed inside.
