That specific thing is not a human universal. But the general behavior is, as far as I know. There are always little lies one is supposed to say. E.g. “no, that woman is not as beautiful as you”, “he looks just like his dad”, “nice to meet you”, “please come again” (but I’ll never invite you). In Russian, in particular, the very act of greeting is often a lie, since it means “be healthy” and there is effectively no way to “greet” an enemy without wishing him well.

In Klingon (fiction alert) the nearest thing to “hello” is nuQneH, which literally means “what do you want?”
