The gas station will be older, crappier. As the shift to electric cars takes hold new gas stations won’t be built, old ones won’t be renovated, and they’ll be squeezed harder. Expect more stuff to buy at worse prices with more advertising.

Chargers will likely rise up around a different type of venue that won’t be seen as a gas station. More cafes, places suitable to spend 15+ minutes. Places with seating.

Increasingly gas stations will just be seen as a dated concept that isn’t living up to the world of 2040. Otherwise they’ll be almost exactly the same as today.
