Clearly there is places where pump theft is not that common or tackled in some other way, because there are countries where post-pay is still the default.

I do know that at some post-pay pumps the cashier has the ability to lock and unlock the pumps from inside

Unmanned stations have existed for quite some time here, they are just not the only way to fuel up.
Manned stations are still very common, if not the default, and if a station is manned it is usually not prepaid.

In the Netherlands it’s a mix of both these days.

During the daytime you pump, and then walk inside to pay afterwards. At night, when the building itself is closed, you pay using the terminal and only then are you allowed to start fueling up

There is also unmanned stations without a shop. They are pre-paid all day by default.
