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

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 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, "indeed I am"

The man replies "Well wash your hands, I want a Cheese Sandwich!"
