I don't use sir and ma'am, unless it's sarcastically to people who are demanding respect without having shown any evidence that they deserve respect. I don't give a damn if they've been alive longer than me- for all I know, they could have spent that entire time making everyone they know miserable. Living for a long time is not that much of an achievement- you just have to keep putting food in your mouth. Anyone who demands respect for that has my contempt.
Of course, I have respect for those who have survived a lot to become old, but in my experience they aren't the ones who demand that I use words that are nothing but lip service to respect. Using those words is all very well, but how one treats people is more important than if one remembers one's social ritualistic gestures.
