There was an engineer who had an exceptional gift for fixing all things mechanical. Afterserving his company loyally for over 30 years, he retired happily. Several years later, the company contacted him regarding a seemingly impossible problem they were having with one of their multi-million-pound machines.
They had tried everything and everyone else to get the machine to work but to no avail. The engineer reluctantly took the challenge. He spent a day studying the huge machine. At the end of the day, he marked a small “x” in chalk on a particular component of the machine and stated, “This is where your problem is.” The part was replaced and the machine worked perfectly again.
The company received a bill for £50,000 from the engineer for his service. They demanded an itemised accounting of his charges. The engineer responded briefly: one chalk mark – £1; knowing where to put it – £49,999. It was paid in full and the engineer retired again in peace.
