He must have thought I was a Dummy or something. Yeah I guess it could work on some foreign people who can't speak English very well and don't know their rights. Just remember, unless you sign your name, you're not obligated to buy anything. And even then, I think there's some kind of a cooling off period of 48 hours or something like that. It allows you to change your mind about large purchases within that time limit. I'm not exactly sure. You need to talk to a lawyer about that.
By the way, the salesman wasn't foreign born. He's a white guy, born here.
