ETA: Do people really spend that much time just hanging around, drinking at bars? I have a hard time imagining it. First, I would be mentally wrestling with how much I was spending on booze. Second, I would be way too self-conscious. Third, eventually I think I'd just be bored and start playing Words with Friends or something on my phone.
