I'm polite with the telemarketers, what few do manage to sneak through. I've signed up on the Do Not Call list, so I don't get many. When someone does call, it's usually from the cable company or phone company wanting me to upgrade my service. Sometimes I agree, sometimes I don't. Other telemarketers, once I realize that they're trying to sell me something, get a "May I ask what this call is regarding". When they tell what it is, I'll either decline, or ask for more info.
I actually had a telemarketer call me last week, and asked how I was doing. I truthfully explained that I was rather busy preparing supper for my family. They said they would call back at a later time and date.
I have a document on my desktop pc that I got off of Netscape, titled "Twenty things to say to Telemarketers". If anyone wants it, pm me and I'll send it to you.
