Nope. My friend is a cameraman who worked on his show. Cordon is atrocious. He shouts at the production staff and ignores junior staff or those he seems insignificant. He regularly yells at camera ops, floor managers, runners, assistants etc and is utterly up his own backside and thoroughly unpleasant.
Usually if you hear multiple rumours about a celebrity's behaviour there will be an element of truth in it since someone like him crosses paths with hundreds of people each week.
It was one of the reasons Her Majesty the Queen earned my respect even as a non-royalist - that despite the reputedly millions of Britons who'd met her and seen her up close over the years not one person ever witnessed bad behaviour, rudeness, snobbery or arrogance coming from her mouth.
