He always comes at the most inconvenient moment, and to be quite frank, I don't WANT to buy any of his stuff.
He's always up-beat (to the point of being over-ingratiating) but if I say a polite "no thank you", he shoots me a look of pure evil because I don't want to buy any dusters, like I'm a totally stuck-up bitch. And then I'm left feeling a bit shitty, because he has got off his butt and is trying to earn a living after all, but I just don't like door-to-door salespeople.
I am intrigued to get some feedback on this.
