Agreed. I know hypnotists can pull off some pretty impressive things in regards to persuasion, but I don't buy the "jewelry store heist" for one second. His MO seems to be to first build a rapport with his "mark" and establish comfort, then to implant a mental suggestion by linking an everyday phrase to his desired outcome. First off, someone coming into a jewelry store and saying that they'll buy a $4500, unsized ring after a few seconds of inspection is going to raise several red-flags in any halfway-competent clerk...certainly not going to help with the rapport or comfort levels. Second, counting bills is going to be a fairly routine part of his day. He's going to know the weight, texture and feel of paper money like the back of his hand - there is NO WAY he's going to accept a stack of paper as the real thing.
I could see the fish market scam being plausible, but not this.
