This person who worked at a steak and seafood restaurant had to deal with the crankiest and most entitled of customers. As the OP shared to r/TalesFromYourServer, some people just do not know how to be kind to service workers.
The writer, u/RedTailFox1957, shared this story from their time as a waiter. They had lots of regulars who were nice, but there was the odd person who would be extra demanding throughout their meal. One story that clearly stuck with the waiter was this one guy they simply called the “grumpy old man” (GOM). He and his wife came in to order some scallops, but the GOM was very, very displeased with his meal. He let out a verbal tirade on this poor waiter — I can’t believe the waiter didn’t burst into tears right then and there! The other customers actually sided with the OP though, after seeing how terribly the GOM was treating this worker.
Next, bite into another food story. This guy ordered a sandwich just the way he thought he wanted it, with EXTRA ONION… so the employees just did exactly as he asked.
