Have you ever kept a scammer on the phone because his/her voice was relaxing?

Not a scam, but a sales call.

I once succeeded in moving a young lady from the subject, to the extent of a very pleasant social chat!

A salesman had been trying to sell me a portable 'phone contract, probably genuinely, but costing nearly twice as much in contract fees as my normal PAYG call fees. Realising he was getting nowhere, he transferred the call to a female colleague.

"Oh aye", I thought, "The charm offensive".

Didn't work!

Yes then I start breathing all hard and then they hang up

I would never.

I hate those people.

Yes I have, but not because his/her voice was relaxing. I did it to keep them from scamming someone else.

I have a collection of scammer's counterfeit checks.

Talk dirty to them.
