> Name another institution where inmates have to ask for permission to go to the toilet, besides school and jail.

Busy call centers, fast food restaurants. Factories: assembly line workers. Chemical plants: process operators.

I don't mean to be snarky but I think you would be surprised at the percentage of the population working jobs where they cannot simply leave their station without permission.

> Edit: or another institution where people can attack you and you can’t call police to help you.

The military: active duty personnel deployed to war zones.

That's a ridiculous statement and has nothing to do with the institution. We have decided as a society that the police shouldn't be involved in petty children's fights. Seems like the right call to me.

Many, many workplaces keep a close eye on when you use the restroom, for how long, and who else is at the same time.

It's disturbingly common.
