Now that Amazon is advertising one-hour delivery of bottled water,

[[A diagram showing the most obvious progression of events.  First just one bottle is sent from the warehouse to a person.  Then two.  Then five.  Then 20.

I vote we start calling municipal plumbing "on-demand hyperloop-style water delivery" and see if we can sell anyone on the idea.
