We would like to hear your story of serving a nightmare patron

A diner in a Sydney restaurant has been caught on CCTV sprinkling armpit hair into their food “in attempt to get a free meal”. After confronting the head chef, the man allegedly then left without paying, having ordered the most expensive items on the menu.

With this delightful story in mind, do you have a story of dealing with a rude or generally bad customer while working in hospitality?
