Sweets, chocolates and crisps were all very well, but to buy them by the checkout, on an impulse, was falling into a trap.

The fact that the sensation of smugness was more pleasurable to me than that of salt or sugar tells you all you need to know about the kind of monster who comes to prominence in modern Britain.””
