I haven’t read the telemarketers thread, but I just want to say as a former telemarketer, I think people should try to be nice to telemarketers. Some people have this mistaken idea that you are allowed to be rude to telemarketers and hang up on them.
Telemarketers are real people trying to earn an honest parnassah and you should be as nice to them as you are to others!
Disclaimer: most people I called were really nice. I am just writing this as a reaction to the above thread that I did not read that I suspect may have had posts encouraging people to be rude to telemarketers and as a reaction to the small minority of people who were rude.
