Was so furious one night when I had to bring my grandmother to emergency. The twit Nurses calling her by her first name - except one older Nurse who called her Mrs …. I made a point of thanking her and telling the other Nurses that when I trained to be a Nurse we called everyone Ms, Mrs Mr or sire or ma’am. We had to wear our hair up it couldn’t touch the collar of our inform which was always white, and we had to wear our hats (ok glad the hats are gone - hated when they fell into the bed pans

), we could wear a dress or slacks but it had to be white.
Each section’s uniforms were a separate colour - blue for housekeeping, yellow for dietary, maintenance guys wore dark blue. Drs wore scrubs or lab coats over street clothes.
One knew who they were approaching to ask a question, these days the nurses housekeeping dietary - they all wear uniforms willy-nilly all sorts of colours and patters you don’t know who’s who!
It ticks me off when someone calls me by my
First name and I don’t know them. And I will call them out on that! Gosh I am an old fart!
