I'm a native English speaker and lived in the US my whole life and this makes no sense to me either. I <i>think</i> it means that coffee automatically comes with one unit of cream and one unit sugar and that saying "no cream no sugar" is insufficient to remove them; instead you have to know the magic phrase "black coffee". My guess that the parent poster is only familiar with their local (NYC?) coffee culture where a regular coffee always comes with cream and sugar and thinks it applies everywhere else too.<p>In any rate, it doesn't matter at the vast majority of places where I order coffee because they won't even add cream and sugar for me if I ask for them-- I have to add them myself from a side counter.
