Rental car Hell (U.S. version, with an American car):
I'm returning the rental car and stop to top up the fuel just outside the airport. There's a locked hatch over the gas cap. Oh, I'll just find the unlock button and I'll be good to go. By the door on the floor? No. On the dash by the door? No. Between the seats? No. I look all over the interior and fail to see the switch. Eventually, I figure that maybe the owner's manual might indicate the correct location. I open up the glove box hoping that the owner's guide is still there. No manual, but THERE'S THE GAS HATCH RELEASE! Inside the glove compartment!
