Yes. I've also known some back slappers. They slap your back and you gotta slap there's a little harder. Soon you're locked in a back slapping match and you have to see it through.I know some people are touchy-feely and it's just their nature, but I knew a salesman that clapped a stranger on the shoulder as a greeting and the guy had something already seriously wrong with his shoulder at it did not go over well at all. Needless to say he didn't make a sale.
