From The Scotsman:
Richard Macrae was given the homemade card for his 30th birthday by a friend as a joke. But when he presented it in shops, bars, restaurants and cinemas, Mr Macrae was surprised to find many retailers agreed to take money off his purchases. "People have always given me stick for my hair colour but now I'm going out three nights a week and saving a fortune. The joke's on them," said Mr Macrae.
