Every pump in the UK is pay after pump, unless it’s pay at pump then you are limited to £99 usually but it’s just a hold, it only charges when you reseat the pump handle. It freaks me out in Europe and the US when I come across a pay first pump, I don’t know how much it’s going to cost to fill up and then I need to go back in to get my change, ridiculous!
If you want to pay cash, sometimes you have to go in and give them money, then they have some way to tell the pump to only put out that much gas. And if you don't pick the right amount, you have to go back in and get your money back.
