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 to 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, I am.

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