Pumpguy, we had a guy just like your screwball. Couldn’t figure out how to start a backhoe (despite them having two at the school he went to), didn’t know the difference between 12 and 24v battery wiring (despite spending a whole day in school on servicing batteries), and had to have his hand held on very basic stuff like services...and anything more complicated, forget it he’d just stare at his laptop with an expression like a chicken watching a magic trick for days on end instead of doing the work. When he did do work it’d take him three times as long as me ( and I’ll freely admit I’m the slowest in the shop)
