I actually can't think of any that would replace sir/mam. Other than inv the military, i haven't actually used sir/mam. Although, i'm sure of you mean respect most people won't take offense. I mean, its a bit disheartining being sir'd, but i get it, and i understand i can' t demand all of society to instantly understand. It's after i tell them i'd appreciate another pronoun and i go ignored, then i'm offended and angry.

I have recently noticed that here in Cali, "dude" has become interchangable between all genders. Not sure if that's the same in other places. And it's not exactly respecting. But, nifty none the less.
