Seriously. It's like if you had an insecure partner who incessantly asks you 10x a day "How do I look?" and if you say ANYTHING other than "FANTASTIC!" you know they're going to react really bad.
Except it's worse since if you ever give an honest answer it's not you they'll berate, the bosses will just flagellate their underlings who might not even be truly responsible for the "low" rating.
