Un-Fun Fieri
Fieri may seem like the kind of guy you'd love to hang out with on set, but apparently, his cheerful demeanor is all an act. Fieri "had ridiculous requests at all hours of the day," demanding his employees work late into the night and refusing to accept plane tickets with airlines he disliked. He would even rearrange shoots to make sure that his hair was properly bleached and coiffed. According to a former staffer on the series, "I don't think anyone actually liked him."
