Being ejected from the premises on Saturday Morning was the first impression i got when they said I couldn't wait for the car. But I suspect it's their awkward way of saying "we will not do it any quicker if you are waiting for it, so stop making us feel awkward by sitting around the place and watching us work". Which is exactly what I will be doing.
I perfectly agree with your comments on sales people knowing nothing about their products. Numerous times I have bought a car, and I knew far more about the car than they did, and I was even telling them about features of the car which they were clueless about.
It's really poor for a sales person to not know anything about the products they sell, but it happens a lot. It even happens at my place of work. I have even heard the sales manager at my place of work quote the classic line of " I don't expect my staff to know anything about the product they sell, I just want them to get through doors" this was during the time when he was employing a rather attractive woman to be a sales rep. As well as being so inappropriate and sexist, it also highlights the thought process of what a majority of people in the industry think a good sale person should be like.
On the flip side to this though, I have known the odd one or two good sales person in my time, and it is then that I feel I would go back to the same person should I want to purchase another car or other item.
