When I was about 16 years old, I worked part-time on Sundays at a "Quick Lube" place, Sunday we worked from about 9 AM straight through to quitting time around 6 PM, sometimes we would get a five minute bathroom, sandwich break, but we were hopping all day, we would have a 4 to 10 car line up on BOTH bays all day. I worked down in the pit, a real grease monkey
Sometimes, we would have a problem, a stripped drain plug a filter that would NOT come off without the hammer and chisel method etc etc. The bosses were two brothers, if there was a problem, one brother would whine, moan and basically throw a fit, cast around for someone to blame (often it was no one's fault) and just make a mess of things, the other brother, would just fix the problem. I learned real fast, which method worked and which did not.
I've tried my best to be the guy who just fixes the problem.
