(A customer comes up to the register with nothing but a coupon.)

Customer: “Can I use this? It says $15.”

Me: “Yes, that will get you $15 off anything in the store.”

Customer: “Okay. I want to use it.”

Me: “No problem. Just go ahead and shop around for whatever you’d like, and then I’ll apply the coupon when you check out.”

Customer: “It says fifteen dollars. I can get fifteen dollars?”

Me: “This is a coupon, so the fifteen dollars will be deducted from the price of whatever you purchase.”

Customer: “Fifteen dollars?”

Me: “Yes sir, all you have to do is go pick out what you’d like.”

Customer: “I want fifteen dollars.”

Me: “I understand, but to get the fifteen dollars off, you must purchase something here.”

Customer: *blank stare*

Me: “Do you have an idea of what you were looking for? I can direct you to the right section.”

Customer: “Fifteen… dollars?”

Me: “Yes. Fifteen dollars.”

(The customer turns around and slowly wanders out of the store.)
