My friend and I walked in, didn't see our friends yet, and walked back out.
As we were leaving, the bartender says "take care guys!"
My friend joe says "we'll be back in a few."
As I'm stepping out, I hear the bartender (Caucasian guy, not skinny, derby hat on), mumbles "I'd rather ya didn't." And then laughs to the customers seated around him.
I looked and made eye contact at the door, and he says "oops, he heard me! Haha!"
Personally I think he was just trying to make his customers laugh to improve his tip, but it was rude.
great prices on drinks though (I know from previous visits)
