A Cheese Sandwich.
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!"
