This would be a good Tumblr accout. Rubbish people say on their mobile phone in a confined public space, although, I’m sure you could find a catchier username…
You’d be surprised how much information you can actually learn from a loud talker and it’s a pretty big security risk in some cases. If they’re nattering away about their holiday dates and the fact their house will be empty, with ‘no one home for two weeks’… doesn’t take a rocket scientist to work the rest out.
I’ve heard bank passwords, security codes, working hours, times away from the house and at work, family functions… The list is endless.
Do everyone a favour and forward this to a loud talker you know and give the rest of us some peace.
