It's kind of like the story of the old TV repair guy that came out after several others couldn't fix the guy's TV. He took off the back, took out his screwdriver, turned one screw just a tiny bit and boom, the TV worked fine. The old TV repair guy, after putting the back of the TV back on, turned and said, "That'll be a hundred bucks please." The guy who owned the TV was outraged saying all you did was turn one screw just a little bit and you're charging me a hundred bucks? The old guy responded without hesitation saying, "It's $1 for turning the screw, and $99 for knowing which screw to turn and how far to turn it." The guy paid him.
