Many years ago I was working on a major US Government project. A (30 year old) "kid" shows up with 100% brand spanking new tools and all new tool chests who did not know the difference between metric and Imperial measure. [According to his paperwork he was a "Master Mechanic."] So, over the first couple of days we sent him on "runs" for: prop wash, a vapor lock key, and a muffler bearing puller -- and he never caught on! He drover more than 300 miles (in his own car at his own expense) and, whichever depot he got to would explain that their last "stock" of whatever item had just been pulled. It turned out that he was a Congressman's kid and, going home for the weekend, his dad got him "transferred" to another project...
