1. The hose doesn't drag on the paintwork because, so no problem filling up on the "wrong" side. You don't even need to park that close, you could park 2 ft forward of the hose and 2 feet out and it will still reach. I don't understand why people queue up so they can have a pump on the same side as the fill point. I'm not British, so I've put this down to the attraction some British people seem to feel for queueing up.
2. The pump they would vacate by moving won't work anyway until they have paid for their fuel.
3. No comment.
4. The nice thing about a disesel with a 60 litre tank is you can drive 500+ miles on a motorway before running out of fuel, so you never need to stop at expensive motorway service centres.
