my comment was more of a jest but I think you might be overlooking some details.

the building the woman is coming out of is an inn. you can see the sign below the window that has multiple crests displayed on it. these were likely the crests of noble houses that had visited the inn and they used it as a way to show "we are a quality inn, look at how many nobles we have served".

it was common practice for the innkeeper to collect chamber pots and dispose of them together to save on time.

not saying you're wrong, but there's always more to the story if you look deeper.
