Hand job

A guy walks into a pub and sees a sign hanging over the bar:

Cheese Sandwich: $1.50
Chicken Sandwich: $2.50
Hand Job: $10.00

Checking his wallet for the necessary payment, he walks up to the bar and beckons to one of the three exceptionally attractive blondes serving drinks to an eager-looking group of men.

"Yes?" she inquires with a knowing smile, "can I help you?"
"I was wondering", whispers the man, "are you the one who gives the hand jobs?"
"Yes," she purrs, "I am."

The man replies "Well wash your hands, I want a cheese sandwich!"
