Huh, you’ve got me thinking now.

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.

I’m not sure I’ve ever seen one that was one-way; but my experience is limited to US, MY, TH, and VN.

In those four at least, traffic can come from either direction so you can have left-handed fills use both sides of a pump.
