They have people who seperate you from your friends before the show starts. They'll get info from you about them and from tbem about you.
If you're feeling fragile after a loss you'll be vulnerable.
I'm thinking of a family member who fell into a similiar trap.
Don't go.
once, in a foreign country, I put my back out and went to see an osteopath - a total stranger. She asked me if her partner (a bandleader, as it happens) could sit in. He put his finger on my pulse for several minutes, then told me something about my past that was completely wrong.
He then told me two more things that were correct. He could not possibly have known.
He didn't ask for money, or anything. His partner did a good job on my back.
