I don't know. Gamers are famous for snaking during games. Assuming you were not allowed to bring snacks and drinks in with you... it would be a natural. I have been in a number of gaming groups where gaming started by eating, either bringing food, or ordering pizza or something.BiggusGeekus said:[Devil's Advocate]
If I were a bar manager I'd be skeptical. The idea is not to get people to play games, the idea is to get them to buy coffee/beer/munchies/whatever. If a bunch of gamers came in for a session of D&D, I'd want some kind of minimum purchase or a table rental fee.

Also, imagine all those times when you are bored because you are not currently involved in what is going on, even for just 15 minutes.... it would be the perfect time to wander to the bar... it is common practice for people to eat/drink just because they are bored.
