Here are five stories that onlookers and workers have shared on Reddit about hungry customers from hell:
I worked at a restaurant that overlooks the ocean with a deck and patio people can eat on, which is very popular because of the harbor view. The restaurant is directly next to a fishing company's dock where they load their catch into a truck, and since that truck is the refrigeration for the fish until they get it to their store, it has to keep running.
It sounds like a slightly louder version of an idling car and personally, I don't see it as that much of a problem and most customers just ignore it. When people have an issue with it and we tell them it's a separate company and we can't do anything about it they either opt to sit inside or enjoy the view despite the noise.
