I really can't stand meeting such a neurotic proprietress.

In fact, I feel that the proprietress you mentioned belongs to psychological problems. In fact, it shouldn't be difficult to work in other companies on your terms. There is no need for you to suffer indignities there. Your boss really doesn't even know the most basic way to make money. I can't think of any way to deal with such people except violence. He's still out of thin air. There's nothing you can do about him. After all, he is the boss. Maybe he can find a colleague who is good at his job, and he is not afraid of not eating, but still listens to the sharp knife upstairs.
