Let me step in before it gets too heated.
I've had employees who thought they could do their job better than me. In fact, I'm pretty sure at some point the whole kitchen knew better. But the place ran, the owners made enough, and we were all paid on time.
There are a lot of aspects that people behave the way they do, and if you see things and don't ask (I don't like calling out) then you can only make it up as you go along.
