My wife saw this thread over my shoulder and reminded me about the first saleswoman who "helped" us when we started looking for our van. She was a jerk. Saw our trade in and told us we would never be able to afford a "Cadi". Since we were looking for a van this was not an issue. Then she told us we would have to leave our car, since we were going to trade it in, for a few days to get it appraised. Complete load of crap. They had the best price on what we wanted so when we went back we sought out another salesman who was very helpful courteous and everything the lady was not. After we signed the papers and the deal was done-having had our trade in appraised in under five minutes-the original woman came up and told our salesman that the commission was hers since she was the first to "help us". Before I or the salesman could say anything my wife called the owner over-he shakes the hand of new car buyers and new car buyers roll their eyes. My wife told him the salesman, not woman got the commission because the woman was a jerk and told the owner the story.
I went back a month later to get a recall-repair done and the salesman told me the woman was let go after we left, because of what my wife told the owner.
I have seen this attitude in so many places that I wonder where it comes from.
