"Fun in the bar" joke

Fun in the bar
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!"
