While at a Ford dealership in the 80's they hired a mechanic by the name of Zach. Big tall guy and he had this huge Snapon roller cabinet with the hutch in the middle. Heck you had to be that tall just to get to see in some of the drawers. Had his own coffee maker and snack box as well. We thought this dude was the "$hit". I think he lasted 3 months. Almost every job he worked on came back, hence we coined the term "zach back" for all the jobs that had to be redone.
