The ORD United Lounge bartender is a JERK

Title basically.

Cards me Everytime (I'm 38 and balding). He will jovially chat and carry on with other bar patrons yet myself (and random other guests) will cause him to drop his countenance and unenthusiastically ask "can I help you?" I respond with "can I please have an (insert drink)?" He moans in exasperation while rolling his eyes as he laboriously prours your cheap (free*) tap beer.

I don't get it, he's rude.

Oh, but if you're a tall blonde he's super cool with you.

Rant over.
