A mate of mine once got a stone chip in his windscreen, he phoned all the "How am i driving" numbers and complained the lorry had flicked up the stone, he got it repaired for free.

It really is amazing what you get if you complain
A guy i knew got all his food free at mcdonalds, kfc, burger king etc because he knew precisely the health and safety laws regarding the legal serving temperature of food and what not.

It was a joy to see him in action.
