FWIW i've had consistently low success with finding friends at bars. Mostly i find people i chat to aren't there with an open mind to getting to know people, at most it'll be a quip here and a joke there, but ultimately they're with "their crowd". YMMV.
> Just don't give up, we don't need hundreds of good friends just a few. Even one or two are better than none.
I totally agree with this sentiment, though.
