I thought of this question because someone joked about double-dipping their hands in the chocolate fountain at Golden Corral and boy did that invoke one of my least favorite paying-for-college memories.
Yes, someone did dip his hands into the chocolate fountain at the Golden Corral. Worse, he was a repeat offender, a man that was at least in his 30s if not older slurping it off of his fingers and all, sometimes while making eye contact with me or my coworkers. Worse, there was no enforced rule against doing so, at least at my location, so my manager just told me to let him do it, don't make a big deal out of it, and hope he doesn't bother anyone else.
That same manager once insisted on me making the place extra clean a little before Christmas, so they insisted that I use double the amount of cleaning bleach in the same bucket. I explained that's not how cleaning works or how OSHA compliance works. I got a write-up. I said that wasn't an offense that qualified for a write-up, and what they said was "thanks for the tip, I'll find something that is. Your word against mine." 
That same manager punched me out early without telling me, because the place wasn't perfect enough before I left over an hour late, missing my family waiting to pick me up outside by that long to go out to do holiday stuff. I did call that in on the supposedly anonymous tip line later, but you can guess what happens when an anonymous tip about wage theft is called in on a manager that already knows who would call in that tip in a "right to work" situation. 
That same manager was fired a week later for embezzlement, and not the cool kind. They were writing up and firing people for months for money missing from the register. I found out when collecting my last check and noticed someone new. 
Store manager was a creepy little old Italian man who staffed his restaurants exclusively with teenage girls he found hot. Well that, and me, but I was a night baker, so he never had to see me except briefly in the mornings. One night I overproofed the bagels (it was real humid and someone took them out early to “make room for a delivery”) and he made a big show of dressing me down in front of the entire staff as well as customers because the bagels were getting stuck in the slicer. They had a tool specifically for dealing with this situation, but apparently he found it necessary to force me to get down on the floor and look up inside the bagel slicer to see the size of the chute and where the blade sat that sliced the bagels.
I told him I understood the problem and knew how bagel slicers worked. If you guessed that there’s a chute with a blade inside that slices the bagels, then congrats, you understand how they work too. They’re not complicated. I don’t have any problem with working on my hands and knees either. I’ll scrub the floors if it’s part of the job. I’ve cleaned up shit for a living so it’s whatever. But this was so clearly a dominance thing and he made sure to do it in front of dozens of people at a time where they didn’t have any busy work yet.
I wish I could say I quit. I should have. But I was new to working and didn’t understand that I would have been okay.
Yeah, but I wasn’t precarious at the time. I was living with my parents and only had a couple hundred dollars in bills a month that I would have had help covering. I’ve since had several moments at other jobs where it crossed a line and I began job searching. But this particular one is the one time I regret not just walking out and never coming back.
