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

She says, "What the hell do you guys think you are doing?"

One of the Bulgarian men says, "Can't you see? Ve arrrre all verrry, verrry hoongry."

The waitress makes a stroking motion and says, "So how is whacking-off in the middle of the restaurant going to help that situation??"

One of the other businessmen replies, "The menu say, FIRST COME, FIRST SERVED!"
