There is no such thing in Australia - every outlet here except maybe very remote rural ones is self-serve and has been for years. But I still pay with cash and refuse to pay with a card. I love fucking with people's minds in retail places.
@Jacko1971 yes - they put a hold on around £100 (it varies between retailers) to ensure you have enough to pay and then you fill up and then it takes what you have pumped. It's essentially the same as if you pay in the kiosk as you will still pay what is on the pump as unless you can prove you didn't get the right amount of fuel there's not a lot you can do to dispute it.
I like to do it myself because they’ve not put the gas cap on tight or left it on the trunk of my car and I had to go back because my car run’s totally horrible without the gas cap locked down
I haven't even seen a full service gas station in 30+ years. When I was able to walk, I would have found it weird and awkward. Now missing a leg, I have to admit it would be pretty convenient.
I'd rather do it myself because I'm not a people person. So the less people the better. But on the other hand it helps provide jobs to people. I actually grew up with station attendants. But they got rid of them all to cut corners.
