Customer: “Hi, why are these towels $4.99, but the others $6.99?”

Me: “The $6.99 towels are 6 feet long, and the $4.99 towels aren’t.”

Customer: “But why are they different prices?”

Me: “That’s because one is longer than the other.”

Customer: “I still don’t understand”

Customer’s Friend: “One is a bath sheet.”

Customer: “What does that mean?”

Customer’s Friend: “It’s 6 feet long. The other one is 4 feet long.”

Customer: “That doesn’t make any sense!”
