What is that little building and what is THAT MAN DOING?

O.K. A little bit of culture shock here.  There is a university nearby on Rue Gambetta that I drive by each morning; and there is a little building out front that looks a bit like a kiosk or a tiny bus stop.  However; as we drove by the other morning, we became apprised of its true nature - a 3 foot privacy screen about 18 inches off the ground, with a man facing the wall behind - obviously leaving a liquid deposit in said edifice.   Hm, TIF - we are not in Kansas, folks.
