Costco and Sam's Club usually have their filling stations set up for one-way traffic, but offhand those are the only ones I've seen that way in US, Canada, Caribbean, and western/central Europe (though the Euro design of filling stations just off the highway encourages one-way traffic, it doesn't mandate it). Haven't driven myself elsewhere.
Here in Finland at least there are a lot of completely unattended pumps that once you exit the road it’s basically just a patch of land and you pull up in whatever direction you want to match the side of your tank to a free pump.
But in the UK where I’m from and just got back from this is maybe less common.
In those four at least, traffic can come from either direction so you can have left-handed fills use both sides of a pump.
