You should be asking yourself why you assume the person would react angrily instead of just politely correcting the pronunciation. If someone accidentally mispronounces my name I gently correct them, while smiling, and I have never once been offended or take it personally. You also assume it is a heavy burden on others to simply call people what they’d like to be called. When it is not. Being angry over this is not a healthy attitude. It’s simple manners to be considerate of others and that is precisely what the person is asking for, nothing more.
