Wow, long thread!!!
I was a telemarketer for three weeks, it didn't pay well, but I was a freshman in college and it paid better than minimum wage, so I was interested in it. My company was trying to sell Kirby vacuums. They cost a small fortune, but are apparently sturdy and durable and can be changed to buff hardwood floors. However, I don't like the idea of spending $2,000 on a vacuum. There where people there who had been calling for years and where making good money off of it. Most often the money was made off of sweet little old ladies, that really got to me, what little old lady is going to need an expensive heavy vacuum, really? I got sworn at and called lots of different things, but I expected it, my dad was never really too nice to telemarketers so I knew what I was getting into. And yes, there were lots of nice people too, who just said no and hung up. I liked it when I would call some young sounding man, who would try to hook up with me, how almost cute

We didn't call off of a computer list, so those zapper things didn't really work because we couldn't be zapped. I always took people off the list when they asked to be, you just realise that you'll never be able to get this person to buy a vacuum so why bother in the future. The most effective way of getting off the list, (at least if I was calling you) was when I was told that the person I was asking for had just died. Ouch, I didn't want to mess with that, so I just crossed them off the list. I eventually had my life threatened by someone I had called, that freaked me out, and I imagine that you all would agree that that is just pushing the rudeness a little to far. I was one of those happy telemarketers, I hate getting calls from telemarketers who sound like they are doing this for the millionth time and aren't putting any effort into it, I always tried to be more personal, without invading privacy or prying. But the job sucked, there was a lot of pressure to sell, I didn't have the heart to push these big expensive vacuums on people, so I quit. Yes it may be the perfect job for some people, and sure I can see how it may be the best fit for disabled persons with few skills or other impediments (learning disabilities, fear of crowds, etc) but it wasn't for me. I never admit to being a telemarketer (face to face that is I don't see this as counting because you guys can't give me the bad looks I would usually get) because no one likes a telemarketer. That's not to say that I wouldn't like that person, but the telemarketer in them I wouldn't.
If that makes any sense to anyone then yahoo...
As for rudeness, it is expected but not really necessary, from the telemarketer or the person being called.
