Good lord, that's a horrendous story. I'm glad I wasn't the one in that situation, I would have lost it! So in preparation for those rare moments it's good to have a couple retorts up your sleeve. In the bartender's case, when he says "Hey kid, what have you accomplished...?" you could have the good ol' "I've accomplished enough to be in this scenario...the one in which you...a 40 year old bartender gives me...the 24 year old gentleman...a f**king drink, and maybe...MAYBE...I tip you...because you obviously need the money." But of course this is if you want to be confrontational and surrender a bit of class, probably a good thing you kept your cool and blew the place off.

My personal favorite was when I was at a gas station going up to the cashier to pay for my things. Cashier looks to be about late 20's, early 30's. Visible tattoos (not artistic looking either, but the "look at me I'm a badass" stupid barbed wire-esque tattoos).

Without a traditional "Hey, how's it going?" greeting, he motions towards the face and goes, "Lose a bet?" Not even in a humorous way either, because then I would have at least shrugged it off and went about my day, he said it just to be a *%%$@$!*$. So I look at him puzzled and take a quick look around the gas station and then back at him and casually say, "lose a scholarship?" Don't think he was expecting that one.

But yeah, don't go back to that bar unless you're looking to raise Hell with management.
