Are the what-have-you’s supposed to wear a sign telling how to address them?
I assume once they correct you and you apologize, then the next time you make the mistake, they can... uhhh, get you fined or fired?
No. This isn't actually about language at all, it's a crude attempt to express political power, and no matter how you address them, it's going to be wrong. The object is to create an atmosphere of terror, not acceptance.
