I am Ma’am. Ma’am I am. And if I order green eggs and ham at the café, you can say, “We don’t serve that here, Ma’am.”
Miss, I’m not. I am not Miss. That appellation is a dis. Take a look, and you’ll see this: I’m 53, not 18. I may be older than I seem, but my days of girlhood are long gone. And to call me “Miss” would just be wrong. So call me “Ma’am;” it’s what I am. You might think “Miss” is hip or flip, but if you call me that there’ll be no tip.
Unbelievably at a restaurant a waiter called my 81-year-old mother "Miss." It's disrespectful.
