(I work on the pizza counter at a large supermarket chain. We make individual pizzas for the customer.)

Customer: “I’d like some jelly babies.”

Me: “Sorry, we don’t put jelly babies on pizzas. What else can I get you?”

Customer: *pause* “Jelly babies, please.”

Me: “Sir, we do not serve jelly babies here.”

(This continues for quite a while.)

Customer: “I’d like some jelly babies.”

Me: “We do not sell jelly babies!”

(The customer then angrily points to an ingredient on the counter.)

Me: “Sir, those are jalapeños.”
