I'm loving this thread! I worked at AZ for several years. I'm just a shade tree mechanic. Did a few engine rebuilds but mostly parts swaps, that kind of thing. On a scale of one to ten, on a good day I'd consider my self a six knowledge wise.
Sad to say but I was probably one of the most knowledgeable guys there. They would hire most anybody who claimed to have at least changed a spark plug or two. The computer was our life line. They kept staffing to a minimum at all times so taking time with catalogs was frowned upon. Just blow the customer off and move on to the next customer in line.
Pretty sad way to run a business if you ask me.
