I wonder if health liability doesn't drive this, at least partially. Also, do Starbucks have dish washing facilities currently? That adds a lot of space to the footprint of their small stores (It looks to me as though Starbucks can currently just about be run out of a hallway). I'm not trying to be critical of the approach, I think it's great, it just seems like there might be some nontrivial costs to implementing it.
