Eh. I suppose. But I'll have to pass on the swill. I'd have to have something a little nicer than that.
It appears you haven't done it right. To properly enjoy a bar, it must be attended with friends. Pre-gaming is a must, however only maybe two drinks worth. Once there, order nothing that isn't a cheap burr. The point of a bar is to socialise and be merry, booze just cuts out the awkward bit at the start. Which is where the fun begins. Make sure to only maintain a "buzz". Falling into drunk can ruin the fun for everyone at the establishment. Ideally, this will last for a few hours, spending about 3$? a pbr, plus 1$ for tip, runs about 25-30$? At which point, proceed to a friend's house and get smashed to your content.
Drinking in public /isn't/ stupid. It merely hasn't been presented to you in a scenario you have been able to enjoy yourself at. I might suggest Tybee Island's Huckapoo's bites and Booze if you're in that area. Great pizza, too. I'm sure there will be an Oktoberfest event near you as well. Try it! You may like it!
tl;dr: go with friends, pre-game, only buy cheap beer.
...not that it matters. No friends to go with.
