I hate to join the greek chorus here but... don't you DARE bring your own booze to a bar. If you can't afford to pay for a drink (and tip), then you CANT AFFORD TO GO OUT. Drink at home! Bringing outside drinks to a bar will get you banned from the bar, not to mention makes you a total asshole. I can't tell you how many "regulars" I've seen get banned because they treat the place like their living room. Even if you don't like the bar owners (why would you go there anyway), you're just stealing money from the server/bartender, who's probably on just as much a shoestring budget as you (or more). Seriously. You can't imagine how much of a trashy asshole this makes you.
