A traveling salesman arrives in a small town, starving after a long day. The only place to eat is a dingy-looking fast food joint, but hunger wins over hesitation. He walks in, takes a seat, and immediately notices the place is as sleazy as it gets. The waitress matches the vibe with her grimy uniform and rude manners. Not exactly the best service.

Still, he’s desperate for food. He orders two hamburgers and a hot dog.

A few minutes later, the waitress returns, carrying the two burgers tucked snugly under her armpits.
Appalled, the salesman blurts out, ‘Why on earth are you carrying the burgers like that?’

She shrugs and says, ‘Keeps them warm.’

The salesman thinks for a while, then says, ‘Cancel the hot dog.’
