I see a lot of those Mormon young men here in Germany on their mission. There are usually two of them, dresses well and behaving very politely. Although they directly contact people on the street, I never have the feeling that anyone is annoyed by them. Therefore I could well imagine that they are great sales men.
Honestly, being stopped on the street and talked to isn't so bad if they're not trying to sell you something. The only reason I ever go out is to talk to people and almost everyone (myself included) is afraid to do it. I've come to enjoy the short conversations with the Jehovah's witnesses, the Hindus and so on even though I'll probably never believe most of what they're saying.
