They ran into the problem where one group of volunteers that aligned to cook together were vegan and insisted on making only vegan food (it also sounded like the dishes were very strange to the locals). This made sense for the cooks, but the locals didn't want the food. But nobody could convince this group to do anything differently.
Their system resulted in a sort of rotating hierarchy that meant every few days they couldn't provide for the locals.
Functional anarchy seems like it takes a lot of work.
