I work in an dress alterations shop.

Client: I need an alternator.

Me: I’m sorry, ma’am, we’re an ALTERATIONS shop. If you’re looking looking for an ALTERNATOR, you need to go to a garage or a car parts store.

Client: (angry) I know that! I need an alternator to alternate my wedding dress!

It was SO HARD not to correct her the second time, but I knew life would be easier if I didn’t.
