I think you are falling for a false stereotype. Gamers are great patrons. I live in Indianapolis and Gen Con is hosted here. Every year I see stories on the local news talking about how the local businesses love the Gen Con attendees. This year I saw the owner of The Ram, a local restaurant/brew house, on the news talking about how great the business was during Gen Con and how his staff enjoyed working during the event. They wouldn't be saying that if they were all sitting around drinking water and taking up space.
