I understand your concern. Things like that shold be duly noted on the ticket and with proper signage at, or near the section.
When I first moved to Arizona, in 1988, I got season tickets for the Cardinals and I got the in the non alcoholic section because Idont drink, and they also were under the overhang which kept them out of the sun.
I have always been a believer that alcoholic beverages should NOT be sold at sporting events because they are the catalyst for many of the altercations that take place in the stands.
I see no reason that any person cant go a few hours without a beer.
This is not intended to pick on you, or any others that may consume a beer, or beers, at sporting events, but I, for one, see no need for it.
There is no reason that any person cant go to a game, be involved with it as a fan, have a good time, and do it without drinking beer.
There is plenty of time for that after the games.
Just my two cents.
