So, I worked a movie theater as an usher (poor bastards that clean after a showing for the next one) for about a year and a half. By about four or five months in management decided I was put together enough to teach new hires. There's one in particular who always stood out.
Anthony (not his name, but why not) was high-functioning enough that he understood stuff like keeping himself clean and not talking about his autistic hobbies unless asked. The night I trained him went well, he was eager to learn everything I taught and he even managed some small talk as we worked. I clocked off thinking he'd do fine.
The next time I clocked in, management pulled me aside, saying I wasn't in trouble, they just had questions about how I taught Anthony. I went over everything and they just looked at each other before saying Anthony was basically just doing whatever he wanted instead of what I taught him. The kicker was that every time someone, be it another coworker or a super, tried to correct him, he'd raise a fit and shout stuff like "You're not my mom!" and "You don't get to tell me what to do!"
Management had figured at this point this was an Anthony thing, and warned me I was scheduled with him tonight. I went into the shift fearing the worse, but that didn't happen. Anthony did as I'd taught him, and I never once had to correct him. The other shoe dropped when he called me "Mr. M3xus" like we do the supervisors and we realized he thought I was his supervisor. Not just any supervisor, his personal one. And so it was that I wound up Anthony's unofficial wrangler. Management always made sure we were scheduled together to make sure he did his work. The new managers that didn't and thought they could wrangle him soon gave up and kept up the status quo until I left that job.
Jerks never did hook me up with supervisor pay.
I've got a few more stories of dudes from that place, but I'll tell them later. It was an interesting place.
