(A customer ‘drops’ a brick, giving it a little chip. He then proceeds to join the line.)

Cashier: “Hello, sir, how can I help?”

Customer: “There’s a chip in this brick. I’d like to get a discount please.”

Cashier: “I’m sorry, sir, only cracks or serious fractures would warrant a discount on bricks. A chip won’t damage the function or stability of the brick.”

(The customer proceeds to lift up the brick and forcefully drops it on the ground.)

Customer: “Now it’s broken! Can I get a discount now?”

Cashier: “No, but you can sure as hell pay for that.”
