Worked at a chicken licken before and 1 like I am spilling. https://twitter.com/IOL/status/1305044479175462912
I will not name the exact location I worked at, but the culture is widely similar across such restaurants. Exploitation, unsafe work conditions and the whole back setup is basically designed to keep you on your feet.
So fryers, I worked as one, I wondered why there was not a single woman on our team and I found out in a horrible way. Your job as a fryers is to defrost, prepare, and fry. You take care of your station/s for food safety reasons. This involves cleaning.
A lot of the chemicals we were expected to use were really harsh on the skin and safety gear was not always provided. I saw my then colleagues wrap their forearms with plastic bags. No goggles, no masks to keep them from inhaling the kak.
I always refused to use the chemicals and it didn't go down well. And another thing I refused to do but wound up having to do was doing work I wasn't employed for. Front tables, front station, and just about anything because "here you must learn how to do everything."

There wasn't space for resting, eating. It was basically a toilet that was converted to such a space. So if you're eating and somebody wants to poop, you are subject to the smell, if you don't wanna go stand outside.
The "remaining chicken" stories you read about, hear...all true. I've heard about them and the fear was ever there. Having a deduction to your little salary fucking dents your sh*t. Thankfully it never happened to me in my time there. But it had happened to a coworker.
I miss my former coworkers so much and I really hope that a lot changes for them. Working like that, 6 DAYS a week, it is not okay.
