Truck stop.
 

A trucker came into a truck stop cafe and placed his order. He said, "I
want three flat tires, a pair of headlights and a pair of running
boards."

The brand new blonde waitress, not wanting to appear stupid, went to the
kitchen and said to the cook, "This guy out there just ordered three flat
tires, a pair of headlights and a pair of running Boards. What does he
think this place is, an auto parts store?"

"No," the cook said, "Three flat tires mean three pancakes, a pair of
headlights is two eggs sunny side up, and running boards are 2 slices of
crisp bacon."

"Oh, OK!" said the blonde. She thought about it for a moment and then
spooned up a bowl of beans and gave it to the customer.

The trucker asked, "What are the beans for, Blondie?"

She replied, "I thought while you were waiting for the flat tires,
headlights and running boards, you might as well gas up!"
