I get the impression this isn't typical, but for me "gas" usually means a 150-gal propane tank, filled asynchronously, often by truck rather than gas main. A benefit of this, like most asynchronous systems, is that no amount of disfunction in the backend will have any immediate effect on local usage.
But yeah- in my neck of the woods, anywhere outside the city has a propane tank on the property somewhere.
Actually, that is a specific thing that this method does help with: if people stockpile in a given month, it has no immediate effect on me, because my gas tank still has gas left in it. It might cause non-immediate problems, but a lack of local buffers doesn't help with that, and I've at least bought weeks or months of time for those problems to clear up.
