I recently witnessed a customer treating a food server at a small Chinese restaurant quite badly. It was a very upsetting because she is such a sweet woman who really takes her job seriously. Next time she was at our table I commented to her that people who treat her like garbage are simply showing their inner self, which is in fact garbage. Indeed you can learn a lot about a person by how they treat people who are in their service.
