Polish Guy buys her a drink

A polish man is sitting at a bar having a few drinks when he notices a very attractive lady sit down at the other end of the bar and order a drink.
The polish guy calls the bartender over and says "whatever she is drinking give her another one and tell her it is on me."
The bartender replies "I don't think you want to do that."
"What do you mean?" yells the polish guy, "Send her the drink!"
"O.K." the bartender replies, "but I don't think it is a good idea."
"And why not?" asks the polish guy.
The bartender leans over the bar and very softly says "because she's a lesbian."
"I don't care, send her the drink." says the polish guy.
So after the lady gets her drink the polish guy very casually strolls down to the other end of the bar and sits down next to her and says, "so what part of Lesbia are you from?"
