You know when you leave Kwik Fit, having tested out the theory that you really can't fit quicker than a Kwik Fit fitter, and you are £400 lighter, but you don't feel you have got anything for your money? For the price of four tyres you could have paid for two weeks full-board in Lloret de Mar for six people, and they would have thrown in a free hospital appointment. It's the same as receiving a bill for light and power which, let's be honest, you feel you already have a God-given right to. Light isn't like beer, you don't 'feel' its value.
