I work in a sandwich store that has a couple of tables. My coworker and I see a customer eating a sandwich with his son. He finishes the whole thing, and then he pulls a napkin out of his pocket, unwraps it, and drops a dead fly that he had in it onto his sandwich wrap.

My coworker and I both share a look because we both know what’s about to happen.

Customer: *Walking over with the sandwich wrap.* ” Excuse me—”

Coworker: “—if it’s about the dead fly we both just saw you drop onto that sandwich wrapper from the napkin in your pocket, save it.”

Customer: *Shocked, obviously not expecting his scam to have been observed.* “I… I don’t know what you’re talking about. This dead fly fell out of my sandwich!”

Coworker: “Okay, so you’re following through. Interesting. I’m guessing you’re expecting a refund?”

Customer: *Now a little unsure.* “Uh… yes!”

Coworker: “Okay, leave your name and number. My manager will go through the camera footage, and if it doesn’t catch you dropping a dead fly onto the sandwich wrapper all by yourself, then we’ll call you for the refund. If the camera did catch what actually happened, though, you’ll be banned for life. Sound good?”

His son starts tugging at his dad’s shirt.

Customer’s Son: “Dad, let’s just go. I told you it wasn’t going to work. This is just sad now…”

The dad left without saying a word after that, dragging his embarrassed son with him.
