Years back I was on a site and the guy who was responsible for health and safety of the company had been demoted to grinder operator to actually do something useful for the day on a all hands on deck job, we had been winching trees ahead and chipping them on a site clearance , we stopped briefly to discuss the next tree and turning around and seeing clouds of smoke from engine oil draining in to the exhaust and him with his hands on his head doing a mad dance around in circles to a rolled machine on virtually flat ground , I looked at the boss and he looks at me and muttered something about the babe can’t even do that without messing it up before running over and turning it off.
