I myself am homeless and once walked more than ten blocks, from Gallery Place to George Washington University Hospital, before someone let me use the bathroom. Metro stations will not let anyone into their restrooms and most stores keep their doors locked. Even the stores I regularly buy from would not let me in, they said their restrooms were closed. Of course, the situation was becoming more urgent as time passed. If I didn’t make it, I would have been too embarrassed to catch the bus I needed.
