Bar in Terminal 3

I was standing at the bar in Terminal 3 at the International Airport
when this small Chinese guy comes in, stands next to me, and starts
drinking a beer.
I asked him, "Do you know any of those martial arts things, like
Kung-Fu, Karate, or Ju-Jitsu?"
He says, "No I don't. And why the hell would you ask me that? Is it
because I am Chinese?"
"No", I said, "It's because you're drinking my beer, you little shit."
