Well, the guy is clearly not in his right mind. Mental issues, some form of early onset of dementia or so...As per some comments on soi4. Must admit i've been there countless of times and it's actually not the place where i saw the worst behaviours, far from it . Mostly people walking around half-bored actually, like in a shopping mall (which it is, in a way...). (ps : i did relieve myself once between 2 cars in Spain after some bad tapas in a seedy bar in Madrid's hot spot. Sometimes it just goes straight through you like a lighting bolt and there is nothing you can do 🙂
