God, I hate US petrol stations. One, nearest to where my BIL lived in New Hampshire, you had to pay in advance, in cash. I was driving a rented Lincoln Town Car, how the hell am I supposed to know how much it's going to cost to fill, how is anyone? Big car=big tank? How big, supertanker big? Could be, but cheap petrol, so could brim it on $5, $50, $150? Another petrol station, another time, lift nozzle, pull trigger, right? No, no, no. Lift nozzle, flip nozzle holder up, pull hidden leaver...(all being announced over the PA by an incredulous clerk who must have thought I'd just been released from prison after a long stretch and hadn't caught up with the modern world). If this sounds like it was some 50s backwater place, no, modern Exxon job, 21st Century.
