Hells Kitchen

Chef Ramsey (spelling?) ROCKS!!

I agree with Pablo - the yelling and swearing are for show and TV ratings. You cannot have several successful restaurants ALL OVER THE WORLD if you are not good at running your business.
 
Watch when he takes someone aside

Watch on his Kitchen Nightmare's series when he takes a chef aside with a bad attitude (yes after first yelling at them) he then builds them back up and motivates them to be passionate about what they're doing again. The person is usually in tears thanking him by the end of the show. He really is good at what he does.
