Does anyone know who this guy is?

A Chef in Florida is caught on tape having a melt down. According to Jacksonville news reports the Chef loses it after learning that he had been fired. He first takes it out on his keyboard then turns on the other workers. Reports say he had a history of violent outbursts and was always mistreating the people under him. In the end he finally got his just deserts! The man saving the day was witnessed by other workers to have said that he was there to help correct the Chef's bad decision by knocking some sense into him. If you have any information on the identity of the man in black who strikes the chef, please contact whoisthisguy3@yahoo.com. There have been other reports of similar attacks.
