this post, Devaka says that once given, the receipient can then enjoy that slice for a whole month. That's my understanding of what he said.
I hate wasting food (real or virtual), but what I think about is that if the slices in circulation were constantly being given new life by being given away, then there is less need to purchase more from the empire. That's not helping to $upport the empire. Am I missing something here?
