We really need to stop normalizing older men just being harsh and mean as leads and bosses. Maybe that shit works in the military, but sir this is a grocery store. I'm just tryna pay my bills dude, I don't need you barking at me.
Also, it just shows a complete lack of emotional maturity imho. A form of toxic stoicism, if you will.
EDIT: Ever notice how a good number of these types of bosses are divorced?
