A guy walks into a bar and sees a sign hanging over the bar which read: 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 enquires 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 f#cking hands, I want a cheese sandwich!"
