We have a very interesting group in house. They bring a lot of business to the hotel. They take courses throughout the week on meditation, palates etc.. When a problem happens I am the first to make it right with the guest. Sometimes there is nothing you can do. A bare foot lady entered the restaurant and ordered a flat bread. It usually has around a 12 minute ticket time. After 8 minutes she came to the kitchen and demanded her food. My manager asked the lady to wait in the bar and told her she could not be in a public area with out shoes. She walked into our bar and dropped to the ground and through a tantrum. All I could do was laugh, ask if she needed a time out and move on.
