I've just read that a young mum was struggling up a London town call steps with a pram. She asked an official at the top of the steps if she could help. The official called security and two large men in hi-viz vests duly appeared. They looked down the steps at the mum and pram and then announced that they couldn't help as they had not received the appropriate training and so could injure themselves! Think I'll invest in a hi-viz clothing company - must be as profitable as the road cone manufacturers.
