That's funny--I've had the same experience as far as 'vibrations' from people who touch an object just to touch but seem to leave behind a negative feeling in the process. Sometimes if I'm wearing a piece and someone wants to handle it, or just reaches out and picks up a pendant, etc., it takes a while for that effect to "wear off."

I think you can pick up on that from sellers, also, the realization that they really would prefer you lean over and look close but not handle it. It's more than fingerprints.
