Hypnotize Complete Strangers !

Hi
Nice to register and be part of this forum.
i want to talk with you about the legendary Handshake interrupt induction
i did it about 4 times with people i know and 2 of them did not have any idea about what im going to do.
i do not believe that it should take more than 3 seconds to put someone in trance and that is what im doing.
The good thing is it worked 100% of the time but if i wanted to do it with strangers what is the success rate ?
my induction is mixed between richard bandler and win mayajid.
