lol, for me I was tired of dealing with the people day in and day out... "Ma'am I understand you need an oil change but it is this much because it's a certain type of fluid" Oh that's crap! You're just trying to screw me over! I was also tired of trying to help people with discounts and instead of trying to hurry it up and get it done I took my time to make sure it was right.... Well I had numerous complaints of that too, that I was too slow and wasting their time. Oh well, it was fun while it lasted LOL.
Edit: at least it got me into cars, and how to work on them so that's a plus.
