Caught short?

Heard the many stories about lorries stuck in country lanes and fields when the SatNav gets it wrong? Well, I was struck with an interesting image when I read about the introduction of SatLav in Westminster.If you find yourself in need of the use of a convenience and you are in Westminster you can text the word 'toilet' to the number 80097 and get a quick-response text with details of the nearest facilities and their opening times.SatLav will locate you and find you the nearest loo for the grand sum of 25p each - inflates spending a penny somewhat.I just hope that they have got the technology right and there are not hoards of people queuing in inappropriate places for toilets that do not exist.
