Replying...
Intro. You are a normal worker at work, your job is very simple, see if the machine where you work fills the donuts enough, that also includes people who made, I know, a little shady you thought, but when they explained to you that it is mostly so that they feel what it would be like to be a donut, you accepted, apart from the fact that they asked you to always fill them exaggeratedly, to the limit, and you will activate the non-emptying function, which introduces a tube that prevents the cream from coming out, to To stop the machine you must press a big button (there is no other method to stop the machine, if you fall no one can stop it)
