A few years ago I was wandering through the fairly new Denver Airport looking for a place to eat. I was rather surprised when I came upon a restaurant that had a public notice warning posted next to it's welcome sign. The notice stated that this restaurant had been inspected and had a major violation. It went on to say that the restaurant was using dirty silverware. Needless to say that impressed me to keep looking. I have never seen this type of notice posted in front of any other airport restaurant, but think it should be requirement, not only at airport restaurants, but all restaurants. The sign should stay up until their next monthly inspection.
Mr. Goldberg was too polite to just go to his seat, I would have felt the blood and commence to do a Mrs. Tiger Woods on the monitor while simultaneously spewing a stream of profanity that would make today's average teenager blush. Then if the airline decided to prosecute me for damage or disruption I would have filed a law suit for negligence and personal injury. Take that you uncaring industry.
I have never seen a store or restaurant at Phoenix Sky Harbor that wasn't immaculate. Perhaps the location of the particular airport and the quality of the management and help make a difference?
