I know of the rights a photographer has (at least here in Germany). It is not so clear cut as it sounds. for example, if I wear a big pink hat in a sea of suits and a photographer does make a photo of me within this sea, even being among maybe hundreds of people, I am clearly the center of attention and he has to obtain the right to use (and show) the image in any way.

You are right, if me being merely some pebble in a sea of pebbles - so to speak.

So there is still some privacy implication left - even in your example.
