My rules: if it's a person I interact everyday, private hello (hi, hey) is ok, and answered with equivalent. If we don't interact usually or have never, if I'm the one starting, then it's "Hi, I'm ..., the one responsible for ... We have this case ... etc etc.". I accept anything.

But, anyways, it's just life, don't know why people (even from my generation) are nervous these days.
