I just read on tripadvisor.com/Travel-g191-c1867/United-Sta… the following advice:
"Most gas stations require you to pay before filling up--even if no sign is displayed. "
This is the opposite of the practice in the UK, so can someone just comfort me by explaining the process? And I hope your advice will stop me irritating anyone else at the forecourt!
Do you park up by a pump, go into the shop, guess how much you're going to need to pay, pay it, and then go back and operate the pump?
Doesn't that make it difficult to "fill her up"? What if you say pay $20, but you miscalculated and the tank will only take $18's worth of gas? Have you blown those $2?
Do the pumps cut out when you reach the amount you've paid?
And while on the subject, are there any places that are usually better prices for buying gas? In the UK, supermarkets often discount their petrol, and even if they're not loss-leading with it, can be relied on to be cheapest in an area.
