Japanese Joke

A waitress walks up to one of her tables in a New York City restaurant and notices that the three Japanese businessmen seated there are furiously masturbating.

She says, "What the hell do you guys think you are doing?"
One of the Japanese men says, "We are all berry hungly."
The waitress says, "So how is wanking off in this restaurant going to help that situation?"
One of the other businessmen replies, "Because menu say, FIRST COME, FIRST SERVED!"
