I just received a landline phone call asking me if I had received and enjoyed my free copy of my local newspaper "The Balham Guardian". Subsequent conversation went something like this:
Me: urm no
Them: but you're at 33 Sanselm Gardens right?
Me: Noooooo
Them: oh ok, can you just help me out with your address then so we can get you a copy?
Me: Nooooo because as we both know you're illegally data fishing aren't you?
Them: ......*long silence*
They could be pretty convincing to someone less cynical than me...
