As a 30 year old I do not mind Ma'am at all, in fact I like it. That is the way I was brought up, and if I ever have kids they will be little Yes Ma'am and No Sir respect givers or else.....and just like Mom said, "You don't want to find out what else is.". Opening doors for people, saying thank you to the waiter who fills your water glass and just thanking people in general seems to have gone away. Sad.
