You don't need a Kubernetes cluster for a little gas station business. You also don't even need the concept of a minimum viable product for that "humble" little success which is more probable for the average person to achieve.
Silicon Valley startups want big achievements. Astronomical stuff. That's why MVPs, PMFs, and KPIs were invented. For doing aerospace science as opposed to building local mud huts.
Chick-fil-a has a Kubernetes cluster at each location. Maybe its not so far fetched. Gas stations are all franchises of a major corp.
The lesser point is that, as things like Kubernetes is for large scale software development models, a small business will find it detrimental to copy Google's internal organizations and practices. They don't have the same genetics and they're playing different games.
And, the more important point, there's no room or space for any new, neo-Google to form now. It's over, as they say. The end of history, I guess.
