Gordon Ramsay
It may not come as much of a surprise that Gordon Ramsay likes to berate people off-screen, too. His foul-mouthed persona isn't as much of an act as one might believe. The former assistant manager at Ramsay's London-based restaurant Maze explained that she once heard Ramsay chew out his assistant over the phone over chairs that had been ordered for a Christmas Eve dinner. "They're so terrible I wouldn’t throw them on a... bonfire!" he screamed.
