A guy sitting at a bar and having a beer called the bartender over.
"Buy that ugly old douchbag at the other end of the bar a drink, will ya?"
The bartender said, "Sir, we do not talk that way about our customers here."
So the guy said, "Well, buy that lady a drink for me, OK?"
The bartender walked over to the woman, told her that the guy was buying her a drink, and asked her what kind of drink she wanted.
She replied, "Vinegar and water."
