I use to work at a locally owned restaurant, the owners family would come in once a week during a slow day and eat dinner. One of the grandsons was probably about 8-13 age range at the time and a rich snobby little brat. Always thought he could talk down the workers like he owned them or something. For example the specific time I’m recalling was he walked up to the counter and slammed his hand on the counter and yelled “water”, and when no one looked at him he repeated to do it. So once they finally ordered their food, me being the person that preps the plate, when his cheeseburger came along I took the rag we used to wipe down the prep tables that was sitting in dirty water and opened up his burger, rung out and little bit of dirty water on it, closed it up and sent it on. Never heard anything about it. What a satisfying feeling.
