I love the structure of the place, the music, and the people that go there. My only complaint is regarding the drags that provide the $1 shots. They are always super rude. I understand the shots are cheap, but for every dollar you spent with one shot, they demmand $1 dollar of tip. So if I get 5 shots, I need to give 5 dollars of tip? It even happened once that I got a shot, and since I was running out of money, I gave 50 cents as tip for that single shot. The drag threw the 50 cents at the trash and said 50 cents? Are you kidding me?
