Once Again From The Top

I work for a big box home improvement store. A young couple comes in.

Customer: “We got a new self-cleaning oven from you guys, and it’s not working!”

Me: “What’s wrong with it?”

Customer: *Angry* “Look at it! There are crumbs all over the top of it!”

She shows me a picture, and indeed, there are crumbs on the stovetop.

Me: “Sir, it can’t wipe the crumbs off the stove. It’s a self-cleaning oven, not a self-cleaning stovetop.”

Customer: “This is false advertisement! I want my money back!”

Sadly, they got their money back.
