You should go tell on us.

I was about 19 or 20 years old, eating at Burger King with my friends, Lew and Doug. At the time, we were still in the habit of taking too many condiments, so my tray and Lew's were both piled with mountains of ketchup packets, napkins, and whatever else they had to offer.

"Hey, Doug," I said, "You should go tell on us for taking too many condiments."

To my surprise, Doug got up and walked to the counter, coming back and sitting down a few moments later. Following shortly behind him was the manager, a middle aged woman. She stood at our table, staring at our condiments and looking angry, but not saying anything. She shook her head.

"That's a real waste," she said.

"Sorry," Lew said, "Do you want us to put it back?"

"No," she answered, "but when you're done eating you can leave!"
