Try pumping in freefall. All your liquids are just floating around. Not like you can put a spigot on the bottom of the tank. Maybe they will do it under a bit of acceleration, centrifugal force, brooms thingies in the tank? It certainly is quite a challenge but I suspect they got a novel idea.
Rural would be huge all the same. Certainly few people will get it individually but it will be common for multiple people to get together and share along with cafes etc.
