“I’m returning this puzzle.”

“Sorry, we don’t do returns on products that have been taken out of the packaging.”

“But there were pieces missing!”

“Which pieces?”

“The corners.”

“Oh… I see the misunderstanding. You can’t get the corners here.”

“What? Where do I get them?”

“At a Corner Store. Duh.”
