I saw this on a TV programme a year or so ago and thought of it today for some reason:
A wages clerk at a small company was working on the payslips when she noticed a mistake with one of the employees wages. As it was his day off but the wages had to be paid into the bank that day she decided to ring him up to check on whatever the problem was.
He answers the phone and she says "hi" and starts to explain the problem.
For some reason though, he is amazed and keeps asking how show knew he'd be there !?
Turns out, she hadn't called his telephone number but used his national insurance number instead. He had gone on a day trip out with his partner and was walking past a public telephone call-box when it started ringing and he'd decided to answer it to see who it was.
What an amazing coincidence ... what are the odds!
