I hate it when people tell their kids to call me Miss Monster or Mrs Beest without actually checking (a) what my name actually is and (b) if it's OK. I think that's discourteous. Also if people call me something and I correct them or tell them what I'd like to be called but they insist on repeating their error. That pisses me off. What's so tough about "your majesty, queen monster, supreme-being above all others"?
No-one has ma'am'd me for a while, or maybe I've stopped noticing. that was way weird when I first landed here (it's Madam in the UK and much less frequently used)
