Law-induced cultural differences will be huge though: where I live there are strict opening hours restrictions and the only exception is "travel needs" and it's not just something you formally register for, you have to operate a pump (or be part of a train station). The result is that the entire market of what is convenience stores elsewhere is owned by fuel stations here and many people suspect that they might actually sell the fuel at a loss to lure people into their absurdly high-margin all-hours supermarkets. But I doubt that "we have a few chargers" would be accepted as a qualification for the "travel needs" exception and then pumps wouldn't be at risk of going away. (the "travel needs" exception lead to some hilarious regulatory quirks for a while, when in an attempt to curb streetside drinking, no doubt pushed by pub owner lobbyism, fuel stations where restricted from selling to people who didn't come by car. They were literally expected to check the parking lot before handing out liquor)
