Well, I personally find title + surname the worst; it's obnoxious and elitist; my (first) name isn't "engineer". I can live with it, though. I just kinda hate people who demand it of others.

So, clearly, you can't please everybody.

By title I mean "Mister", etc. Perhaps "Engineer" is a German thing ;)

And then you must know (if this is a system: store) the person's preferred gender, and in some cultures marital status.
