Completely different type of work, but I once quit a new job at a factory after two days. First day, I arrive early to fill out the paperwork and watch the HR job safety video. Video finishes and I wait for the HR person to return. After a few minutes, I go look for her, but can't find her so I go back to the video room.

Eventually someone else (upset) comes in and tells me that I'm supposed to be working rather than sitting there. I tell him I'm waiting for the HR lady to come back. "She went home for the day." Okay, I have no idea what I'm supposed to be doing. Guy gets even more upset, takes me to the back room, points at one of the other workers, tells me to do what he's doing, and then I never see him again.

The only time anyone talks to me is (a) to tell me every couple hours I'm doing something wrong, (b) tell me it's break time, and (c) to shout at me for coming back from break two minutes early. (c) was my supervisor, and that was the only contact I had with him. When the second day was just like the first, I decided I didn't need that job.
