When business is slow and I want to have some fun, I antagonize these phone solicitors for as long as they want to stay on the phone.

..and I'm brutal.

and still get "Can I just give you our rates"

I absolutely HATE these types of calls at dinner time, which seems to be their favorite time to call. I will always answer and let them say something. As soon as I recognize it as a PITA call, I say: “Hold on just a second, my wife needs me to get the door for her.” whereupon I set the phone down and go back to dinner. I have no idea how long they wait.

I set the receiver next to my computer speaker and play the mp3 file of Gunnery Sergeant Hartman’s (R. Lee Emery’s) “welcome speech” from “Platoon”. (I don’t know how long they listen ... I just hang up the phone when the speech ends.)
