I also don’t go out much, so I might be biased lol

I think different regions have their own customs, since there isn’t really any universal standard for this sort of thing. From what I’ve seen living in New England, most people don’t use the honorifics at all and just refer to people by name or as “you”. The only time I get called “sir” or “ma’am” is by older people working in retail (and half the time they get it wrong, which never feels good)
