I just waste there time
let them get half way through their pitch and i say hang on a sec
come back i siad sorry i had to get a Beer for this one
then they get half way through hang on i say someone at door
come back say sorry could you start over please
I keep doing that until they get the message
You and me both. I will sit there and listen to the ENTIRE pitch 3 or 4 times, giving them just enough to think they can sell me something. My wife gets pretty frustrated about it , but I figure the more time they spend on the phone with me, the more money they lose.
