Totally Free From Thought, Part 2

(We have a rewards card: one stamp with every purchase and every five purchases, you get a free doughnut.)

Customer: *picking up a rewards card* “What are these?”

Me: “One stamp per purchase. Every five purchases, you get a free doughnut.”

Customer: “Oh, okay, I’ll have a doughnut.”

Me: *stamps card*

(Customer walks away, comes back a few minutes later.)

Customer: “I’ll have another doughnut.”

Me: “Glad you liked the first one!” *stamps card*

(Customer wanders off again, comes back again… and again… and again…)

Me: “You know you’ve just spent $18 when you could have gotten the $14.95 pack?”

Customer: “Yeah, but this way, I get a free doughnut!”
