So apparently that piss smell wasn’t actually from the open sewage.
It was because before cars took over horses were the primary mode of transport for people who could afford it, and horse piss is absolutely rancid smelling if it lands on something that doesn’t just absorb it like dirt or soil.
Ok but how funny would that subplot have been if she was pushing a fucking hotdog stand around king’s landing and exactly nobody was addressing it as if it wasn’t the most normal thing in the world?
