It's 6.30pm and I am sat at my desk, guiding a complete stranger through the streets of London via the telephone.
The poor thing had to drive up from Kent to deliver something to our office and got hoplessly lost trying to get home. She was nearly at the Blackwall tunnel when she got lost in Londons maze of one-way systems and ended updriving miles in completly the wrong direction.
So with the aid of google maps I have been guiding her in the right direction for the last half an hour - luckily for her I had decided to work late!
She's told me she's buying a Sat-nav first thing tomorrow morning.
