Derren is a master of suggestion, he could of just told the dude he didnt have a camera and he would have believed it.

Convincing a door man he was on the level is one thing, but i refer to the aftermath. A man makes over 100,000 pounds on Roulette with his first bet then just walks away? No whoops of approval or celebratory drinks?
A casino is going to be a little perplexed by that. They'll look into it, hear about the show through the media and go from there. I'd have thought Derren would then have ample opportunity to prove he was a master of suggestion by trying it on 12 good men and true.
