Only done it once in a pool car. Luckily, cost me nothing as the agent had a more lucrative job rather than towing me 80 miles back to work, and they did the pump out for free. Family has one petrol and two diesel cars so since then, before filling, I have a 'method':
Check price of fuel on big display when entering forecourt
Check nozzle before picking up (green or black)
Check same price appears on display as you were expecting.
Check again correct nozzle is in tank, and only if all boxes ticked begin to fuel.
Others may have their own method, but seems to me more prevalent with pumps with 4 nozzles - normal and super fuels of both types. On these it's easy to pick up the premium priced nozzle too.
