Crusty Old Biker

A crusty old biker, on a summer ride in the country, walks
into a tavern and sees a sign hanging over the bar, which
reads:

CHEESEBURGER: $1.50
CHICKEN SANDWICH : $2.50
HAND JOB: $500.00

Checking his wallet for the necessary payment, he walks up
to the bar and beckons to the exceptionally attractive
female bartender serving drinks to a meager looking group of
farmers.

‘Yes?’ she inquires with a knowing smile,
‘can I help you?’
‘I was wondering,’ whispers the old biker, are  you the young lady who gives the hand-jobs?
”Yes,  she smiles and purrs, I sure am.’
The old biker replies, ‘Well wash your hands. I want a  cheeseburger.’
