Sacred Haven of Debauchery

A colleague at work told me that in Paris, some homeless person (or maybe a taxi driver, I don't remember) approached him and asked for a cigarette, and then started to pee, apparently even in his own pants.
He also said that it smells bad there. I even thought that maybe he went to Yekaterinburg, not Paris.
Overall, he liked it; he lived in Europe for a couple of years, in different countries.

I was there last year. I can confirm that in Paris, if you move just a few dozen meters away from the main streets, human excrement is lying right on the sidewalks. And the metro underpasses are filled with makeshift sleeping places that no one is going to remove. The smell is, of course, appropriate. In some places, the railings, etc., are stained.

Moreover, colleagues who traveled 15 years ago say that it was exactly the same back then; it is not related to the influx of migrants in recent years.
