My boss is an elected official. His name is not hard. It's not unusual. If you want me to take your call or email seriously, the bare minimum you can do is spell and pronounce his name correctly. And if in doubt, you can always just call him by his position (ex: Chairman, Congress Woman, Council Member, etc) or ask for clarification.
And I understand that my last name is not exactly easy. You may call me Leah, Ms Leah, or Ms MaidenName if Ms Maid-MarriedName is too hard. Heck, if you can pronounce my married name, I'll even respond to Ms MarriedName. Ma'am is also fine. I don't particularly care for Miss or Mrs, but I won't correct you. I will correct you if you call me only by my last name (either of them) as I'm not in the military or in law enforcement.
But my name is NOT Missy, Young Lady, Baby, Little Girl, You Stupid B-word, or anything else that initializes or disrespects me.
