We game at my place. I have never gamed in a FLGS and I do not see a reason too.
I have friends who run their own gaming store now and they made an effort to create an area for gaming, although they play DnD themselves, no one ever runs a DnD game there. They prefer to have magic or warhammer games at their store because those are the people most likely to spend a lot of money while there. They have regular nights for all games other than RPGs even though they mainly play RPGs...go figure. In any event, anyone cussing in the store must pay them a dollar. They do not allow it because a lot of kids and families fequen the store and it hurts their image (they sell a ton of puzzles and boardgames in addition to gaming supplies.)
The only other game store in the area I have seen that allows gaming is THE stereotypical gamer haven. The people who frequent the shop of both freaky and smelly and my wife refuses to ever go there again due to some very sexist comments made while she was perusing that RPG books. The comments were made by the owner, who did not know she was there, but that really did not matter. The LG players who were there really freaked her out. Heck, they freaked me out too. In addition, the store owners/ staff must have never learned how to use a vaccum or to dust. The store is dirty as heck and this is there new location. (The old location was in a basement of a shopping complex near a university.....walking into that location took years off your life.)
So I cannot imagine actually gaming at a store. It's far more comfortable to game at home.
