It's also a cultural thing. Just the other day I was minding my own business on a relatively central street in the European Eastern capital where I live and all of a sudden I see a Roma lady, in her early 50s, reasonably well dressed, coming towards the lightning pole that was on my left side, taking her underwear down and urinating, literally in the middle of the sidewalk, in plain daylight. Before that she had been talking with some acquaintances of her just outside a court-yard, I presume that if she really wanted to she could have asked those people if she could use their toilet.
