A man comes into the restaurant and doesn't immediately get served so he complains and asks to speak to the manager. He then continues to explain to the manager how he didn't get served because he was Jewish and calls him a Nazi. He later receives his meal free of charge and doesn't bother to tip the waitress. - A perfect example of a CFJ
