'Diners have become insufferable pricks': Restaurant owner fumes over customers' bad manners causing 'death of hospitality'Too many diners are becoming "insufferable pricks", the owner of a renowned London restaurant has said. When did an unbearable percentage of the general dining public become such insufferable, entitled, unforgiving pricks? Last-minute cancellations, complaints, unrealistic allergy demands and "loudness" were just some of the gripes that made up his list of issues with customers. If something comes up and some can't make it, let the restaurant know. It's rude, it's inconsiderate, it's financially damaging, and frankly, it'll be the death of hospitality," he added.
