First of all, I love your QOTSA avatar.
Well done for getting through it! I think it's really nice of your girlfriend to get those tickets for you both, and she probably didn't realise it was a bar. The thing I have to remind myself to accept is that alcohol is everywhere, I cannot avoid it. It will be at every gig, comedy show, theatre I go to. I just have to deal with it and make sure I have a plan to not drink.
At least you both know from now on
