The other side of the story...
I have to make a lot of phone calls now, selling for a bro's new company. I am a head hunter.
I am so grateful when they say "thank you we are not interested."
Then I get to cross them off the llist.
I am calling other companys- not homes- and I am shocked at how rude some of the employees are. More than once I have wanted to call their admin and tell them how their employee reacted to my question.
Just remember the people on the other line are just moms, or students working for minimum wage.
However...if they start going in for the hard sale- hang up on them!
