I had something similiar, but not quite that bad about 15 years ago at a certain Ford dealer in Everett, Wa. I started asking a sales man a few questions about financing and trade in values of what I currently was driving. Then he asked me "if we could work a deal right then and there, would I buy this car?" I said not right at the time, I was shopping around. He said "ok" and walked off, before I finished asking my questions. I had to chase him down (there's a switch!!) and asked him if he would just answer one more question, which he reluctantly did. The place was not busy, and almost all the salesmen were standing around with their thumbs up there asses, including this jerk.
Needless to say, when I did buy a car, it wasn't from them.
