(A well-dressed woman enters the store and hands me a note.)

Customer: “Could you get this order ready for me, please? I’ll be back in ten minutes.”

(I look at the note, but it’s blank.)

Me: “There is nothing written on this note.”

Customer: “Well, I decided to surprise myself today with my purchases.”

Me: “Okay…that’s new, but I’ll see what I can do!”

(Ten minutes later, she returns.)

Customer: “So, what did I buy today?”

Me: *hands her a bag* “Three pounds of bread crust to feed the ducks in the park. They are free of charge.”

Customer: *surprised* “Oh! I was planning to go to the hairdresser, but this is…DUCKS, YOU SAY? Well, off to the park, then! Goodbye!”
