There was a story years back about a big old diesel engine that wouldn't start. The engineer was called, wandered around for 10 minutes then gave it a tap with a hammer; upon which it started right up. A few days later the engine owner received an invoice for $10,000. Fuming, he called the maintenance company; "10 grand to hit it with a hammer?" The maintenance company replied "It's $2 for hitting it with a hammer, and $9,998 for knowing where to hit."
