Me: “Your total is $42.98.”

Customer: “Wait, that can’t be right. Those pillows are on sale.”

Me: “I’m sorry, ma’am. We just got these pillows in today. They won’t be on sale for at least a few more weeks.”

Customer: “That’s ridiculous! They say they’re on sale! You have to give me the sale price.”

Me: “Well, I’ll double-check for you, but I already sold a few others today and no one else paid a sale price for them.”

Customer: “Are you calling me a liar? Because I already checked! They all say they’re on sale!”

(She points to the price tags on the pillows that have been haphazardly covered up by sale stickers.)

Me: “Yes, and those sale stickers also say that these pillows are napkins.”
