Customer: “Excuse me, but I have a complaint to make.”

Me: “Oh, sure. What’s the matter?”

Customer: “I heard a group of teenagers over there talking, and they said the cake that you serve is a lie.”

Me: “…”

Customer: “What exactly do you have to say for yourselves?! I come in here, expecting to find a decent establishment, only to find out you are selling fake food!!”

Me: “Um, ma’am. They were repeating a popular phrase from the internet. I can assure you, the cake that we sell very much exists.”

Customer: “Prove it! Show me this cake.”

Me: *points*

Customer: “Oh. In that case you should write a letter to the internet about how they’re making up rumors about your products.”

Me: “I’ll… I’ll do that. Thank you.”
