I grew up with a very posh, well-off grandmother and was dragged to expenisive balls in high-heels and ballgowns (it stops being fun after the first 20 parties) as an 8 year old until recently.
I used to have to call all the males there (up until I was about 14) Sir until they gave me their name and said i could call them by it. At my old bording school all the teachers were Sir or Ma'am too.. and that wasn't even that long ago since I'm only in University now

So maybe subs are just polite -laughs-
