Do Chris Angel crew really pays the audience on their videos?

I'm a big fan of Chris angel but I'm not pretty sure of what's really going on behind the camera, i know for sure it's all illusion but I'll be more amazed if I'd know that they really pay the audience just to have some pretty convincing reactions. Do they really pay their audience? especially the trick that chris try to hypnotize all the people inside the restaurant. can you tell me about it? :)
