As I mentioned in the other thread, a nearby Chevron gas station has one along with a floor pump and a vending machine with tubes, patch kits, lube, sunscreen, fiber spokes, etc. I took a few pictures when a group of us rode by it shortly after it opened:

But I doubt it sees much business - the odds of needing something and also being close enough to this station are pretty small. Unless they were very common I'd expect most cyclists to still plan on being self-sufficient and carrying most of what's offered at this kind of station.
