Pissing on the street,when the urge comes

Just imagine a city like Buenos Aires, millions of souls, each with their own tragedies, comedies, hopes, fears, and urgencies. Among those urgencies is one common to both men and women: urinating. If you look like a fairly decent fellow, with enough money in your pocket to buy a coffee or a sandwich, you just go in and do what you have to do, where you are supposed to do it, and usually you can do that with no hassle. But if you are poor the owners of cafés and bars will look at you in disdain and perhaps send you someplace else to dischage that liquid pressing to be liberated. Or maybe, if you’ve had one too many the night before, you just don’t think about what is proper. You open your zipper at the nearest fairly excluded niche or street corner. No reason to get pissed off. But...why can’t the city provide public bathrooms?
