how or what do feel when telemarketers or researchers calls your house?

I find that if its a survey or something then I don't mind talking to someone on the phone. What annoys me is when its a foreign call centre and I'm struggling to hear because of the accent and bad line and they are trying to sell me something I don't want.

I love it when they call because its the perfect oportunity ((sp??)) to be as rude as you want to be and just give them aload of stick, its like when the people come do your door i get a thrill out of slamming the door in their face because they are the people where you can be rude as you like and they go "thank you ofr your time sir/madam"
