Whenever dining at a sit-down restaurant, I find that cold and/or freezing bathrooms usually lead to a bad-mediocre meal with parallel service and atmosphere. I have no idea why, but it has become more of an omen than anything than just a fluke in the heating system. I guess, in a way, I feel like the front and back of the house are equally and important---but other areas tend to be overlooked.
Has anyone else had this experience? Or finds signs previous to a meal that especially irks them or makes them wary of the establishment?
