Excuse me... But my name ain't MA'AM... I have a name, use it or ask for it!
I cannot stand it when people refer to me as Ma'am or men as sir. We have names, fur the love of pugs, USE THE NAME ya know like, Trollcat or Jill, or JAKE.
If you dont know the name, ASK otherwise call them anonymous... Ya, like this, HEY YOU ya anonymous person with the black shoes and cute top.
