I had an experience like that. The salesman said one thing and said a different thing later on. I corrected him and he came up with an excuse saying that he never said anything like that before. While everyone was checking out the new civics and the accords I got up and yelled right at his face and said "are you calling me a ******* liar?!" and went off on him. He turned pale and everyone at the dealership that went to go buy new cars just kinda listened to what I was saying and left.
