Nut The Kind Of Thing You Should Forget

(I am working at our customer service counter when a lady walks up.)

Me: “Hello, ma’am. How can I help you?”

Customer: “I would like to return these.”

(The customer hands me two cans of almonds she had bought on sale. I notice they are open, so I ask if anything is wrong with them and if she just wants to exchange them out.)

Customer: “Oh, no. They were fine. I just forgot I was allergic to nuts when I bought them.”

(I just kind of stare at her.)

Me: “Oh… okay.”
