A guy walks into a pub

A guy walks into a pub and sees a sign hanging over the bar which reads:
Cheese Sandwich: $1.50, Chicken Sandwich: $2.50
HJ: $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 HJ?”
“Yes”, she purrs, “I am.”
The man replies “Well, go wash your hands, I want a cheese sandwich.
