You can sell something at a markup but a gas station sells so many $50 fill ups per day compared to an EV station, the gas station probably has about 1000X more revenue.

Sure their margin might be better than a razor-thin gas station margin but for the time being it's a miserable business. Unless there's another incentive, like selling cars.

So yeah. Like the poster said, there is no incentive for 3rd party EV chargers to be dependable.
