Doubly Problematic

A customer approaches me at the customer service desk and starts complaining about a cashier who just checked them out.

Customer: *Pointing at her receipt.* “Look! I’ve been overcharged here! It should be buy one, get one half price, but I’ve been charged full price for both! She screwed up!”

Me: “I can fix that for you right now, ma’am. Sometimes the machine won’t automatically apply the discount if you’re buying two of the same items but at different sizes, like you’ve done here. I can do that, though.”

Customer: “Why didn’t the cashier explain that to me?!”

Me: “A lot of our cashiers are new, to prepare for the holiday season. As a result, they’re all still learning the ropes. Some people make mistakes, and for that we are sorry.”

Customer: “Well, that’s not my problem! I’m a customer!”

As I’m doing the refund, the customer’s young son runs over to an item display, kicks it hard, and stands there as it all collapses around him.

Me: “Ma’am, please stop your son from doing that!”

Customer: “He’s autistic!”

Me: “Well, that’s not my problem!”

I admit, I said that before thinking better of it. She glared at me but didn’t say anything as I gave her back her receipt and refund note.
