As long as I remember anyone female, child or adult, was addressed as "hen" in Glasgow. Boys were called "son" by people who were patently not their parents, which made me wonder as a child why these people said "hen" to me instead of "daughter". Some did say "lass" instead of "hen".
I find it annoyingly familiar as an adult to be addressed in this manner, or by my given name by total strangers who happen to have heard or seen what it is.
Usually, I put up with it, but I would greatly prefer us to revert to being Mr or Mrs + surname, or Sir or Madam in shops, public offices and hospitals.
