Matinee Pay Day

(I work in a movie theater. Like most theaters, evening showings are more expensive than matinee showings. I have a woman come up wanting to exchange her matinee tickets for evening tickets.)

Me: *after putting the transaction in the computer* “All right, that will be four dollars.”

Woman: “That’s ridiculous! I already paid for these tickets! I don’t owe anything!”

Me: “I understand you already paid for them, but since evening tickets are more expensive than a matinee, you owe the difference in price.”

Woman: “I told you! I already paid for these tickets! I don’t owe anything!”

(I tried several more times to explain why she owed more money, but she was not having it. I finally had to call my manager, who gave me permission to give her two child tickets, which are the same price as a matinee.)
