We were eating out at a well known carvery restaurant yesterday and as the chef served my DD she asked for an extra Yorkshire as they only allocate one on the plate, she then also requested if she could have some of the fresh meat as she had been given the last scraping's and to be fair it was rather fatty. He then began to mutter under his breath that she was a 'pain in the arse' and that he was 'never serving us lot again'. We calm calmly carried on and didn't confront him but am I overreacting or is this extremely unprofessional and rude behaviour?
