Me: Hello… hello… hello…
Other end: Hello Sir. You have been selected to receive a new mobile phone. It will be sent to you in the next couple of days.
Me: Oh, ok. So I put it in the bin?
Other end: (after a moment)… ah, why would you put it in the bin?
Me: Because I don’t want it.
Other end: Why don’t you want it?
Me: Because I already have a mobile phone.
Other end: (after another moment)… oh… ok… bye.
So was he calling from India or China?
Good response. Anything that stumps them and gets them off the phone.
