That doesn't actually seem that different than the "put a hand on the arm while talking" technique that a lot of people use to try to inspire confidence from others.

Personally, when someone touches me like that, I realize I'm being manipulated and instantly like them less.

But a lot of people respond strongly and warmly to touch, even from strangers.

I also dislike it when strangers use my name before I've given it to them, and really, really dislike it when a stranger decides to use a short form of my name instead of the full version that I gave them. It stems from the same distrust of people trying to gain my confidence without merit.

I did not downvote you, and disagree with those who did.
