I waitress in a local restaurant that a lot of much older people frequent. One afternoon a man came in and ordered mashed potatoes with his sandwich. When I brought out his food, he took one forkful of the mashed potatoes and complained they weren’t hot enough. I obligingly took the plate back and put his mashed potatoes in the kitchen microwave for thirty seconds. Still, the mashed potatoes didn’t satisfy him. Annoyed, I threw the potatoes back in the microwave for 6 minutes. They were scorched around the edges and bubbling. I knew I probably shouldn’t have brought them over but I did. To my shock/horror, the man dug into the molten mashed potatoes and ate them without wincing. He tipped me double the tab.
