That city must be full of stank!
The worst stank I've ever experienced was in Africa. You might think it'd be someplace in the jungle humidity of central Africa, but it was actually in Cairo in 1974 when I got out of an air-conditioned taxi in front of the Meridian Hotel.
WWHEEEWWWWWW! I like to fell over right there on the street. And this was a reaction of a Montana ranch kid who'd mucked out many a barn stall. What I learned later that evening over a giant bottle of Egyptian beer (which wasn't bad, btw) confirmed what I'd observed coming in from the airport. When it was time to go, men or women on the street - and there were thousands all over, it was a crazy busy city - just squatted down and let 'er go. No TP, of course, there were convenient water hoses and such around, which just turned into juicy flowing sewer streams in their own right.
Don't ever shake hands with an Arab left-handed.
