I didn’t grow up with the habit but learned it in the military: saying “sir” and “ma’am” when appropriate is also good manners. I’ve also found that older women, especially, find it endearing.
My buddy and I were sitting at the bar...The bartender came over..."What can I do for you ma'am?"
I ordered my drink.
My buddy turned to me and said...."Remember when the bartenders used to call you honey?"
I'm 80 now. Endearing...me thinks not.
I grew up in a career military family, and I called my father “Sir” and my mother “Ma’am”.
Same with other adults.
If my father asked me a pointed question such as “Do you understand?” if I said “Yes” he would approach much closer and say in a louder and harder voice “Yes WHAT?” to which I would immediately respond “Yes Sir.” in a respectful tone. I never dared to do it in a disrespectful tone.
My father was not a violent or mean man. But he had a distinct dislike for disrespect and insubordination. He never hit us for that, his tone of voice was more than enough. It was a very deep growl, and very threatening.
My wife (who had no military exposure growing up and is from New England) often hears me address adult women as “Ma’am” and younger women as “Miss”. She says it sounds odd and quaint to her, but...that is how I grew up. Heh, SHE doesn’t like it when someone calls her “Ma’am”, but I made it clear I am not changing!
