Almost every pump I've ever used in the UK can reach to the far side of my car, so I don't even think about which side to go anymore.
Lots of people do though, and many petrol stations have big signs to try to educate people that the hose will reach if your filler cap is on the other side of the car.
Of course, if you're driving a big van that's not going to work out (and lorries have their own pumps and their own problems), but most cars is fine.
