Japan is famous for the fantastic and various things you can buy in vending machines -- often standing in the most incongruous places. China has a few of these as well. This drinking-water vending machine was standing on a tiny back alley in Suzhou, a city near Shanghai. I couldn't tell where/what it was hooked up to, but many of the homes in this area of the city, which neat and substantial, had no plumbing. So perhaps rather than have a spigot with unlimited water, they decided to meter it out. You bring your 5-gallon jar and fill 'er up. Don't know how much it costs.
