Any idea what the guy in the photo on the top left is doing?
He is a bread delivery man, like the one below:
This fellow has lost a round of bread, and a kind citizen has dusted it off and is putting back on the rack. Yes, that is why you sometimes bite into bread here and think/say, "Hmmm, gritty."
I'm not sure what the guy with the green cart is selling. The cart and donkey driver is a trash collector, and the man with the yellow Dayun get-up sells foul,* an Egyptian specialty made from fava or broad beans.
* Pronounced kind of like "fool," the O's stretching out just a bit more.
