I'll be uncharacteristically nice in this venomous thread and suggest that the few quarters for games/beer are not worth it in the long run. Friends will have a lot of fun coming over and playing to their heart's content. And I like hanging and having my machines (4 pins, 2 arcades) enjoyed! Way back when (loft buildout phase) I got a kegerator to handle the beer needs. When I invite friends over, they still bring beer or other drinks, even though I tell them there's no need to. The bottles/cans add to variety from the single tap (currently Blue Moon). OTOH, if people are hungry and want to order food, I usually let them pick up that tab. Although I put out munchies so nobody is that hungry.
Tonight I'm having another gathering here, about 10-15 people, mostly from the local pinball league. Looking forward to a fun eve of drinking and playing! (Last gathering went to about 3am.) It's all about having fun with your friends and games, together.
