24 hour convenience store in a small town. The manager was a lazy asshole. People would always just not show up for work (huge staff turnover) and I'd end up stuck there for double shifts. When I finally quit that place I just locked it up and left at like 4 in the morning when yet again the morning staff didn't show up. People have lives outside of low level jobs. The job would have been fine without the shit manager and resulting problems.

By the same token the least demanding job I ever had was the one right after that. Video rental store on the morning shift (9-4 weekdays). Nobody went into those places at that time of day, so for the most part all I did was screw around watching movies all day and got paid for it. A few regulars did come in, but they were all weird folks and fun to talk to anyways.

I went through all sorts of crazy positions before I was an adult, those were just the best and worst.
