Market researchers at your door?

But it never stops at 10 minutes, they can still be talking to you 30 mins later, and that's where the problem lies; most people just don't have the time to spare. If they come to my door I just refuse politely to talk to them. I think it's an instrusion of your privacy anyway, and think they should do their market research in shopping malls - people are more willing to stop and talk there anyway.

Well I never invite any strangers into my house, - especially if I am alone. If they show their credentials, and seem genuine, and I have some spare time, I may chat to them for a moment at the door, but that is all. I always try not the be rude to them, because they're only ordinary people doing a job, and trying to earn some oney, the same as anyone else, but I do get impatient sometimes.
