I have done Autoparts, no money (except they give you $.50hr raise when you put in two weeks notice because you just got hired at the "other parts store") the hours suck, people are rude (this is the other job where you can deal with the scum of the earth all day). But it is fast paced and I learned a lot of what I know about cars from working there, I cried all the way home when I quit.
I was a COP for 5 1/2 months, but became one of those guys they tell you about on your first day of the academy, "he got fired because he was badge heavy" (this is not the truth about me but if you heard my story you would think so). My certification is expired so I milk the clock down at the Dairy,(high school required only) it makes me $40k+ a year, enough to pay the house payment, and put gas in the truck that is almost as old as I am.
