Cap't Bob. I've heard the same. Perhaps I should have been more direct in my previous posting.
I was raised in a Norwegian farming community. My father--who I believed was as free of pejudice as I--used to speak of "Jewing Down" salespeople, which was his way of negotiating a purchase. On entering the world, one of the things that I had to leave behind in my home town was this expression. Live and learn.
