Side note there - never try using the HGV pump to fill a transit van - diesel does indeed go everywhere
Although it takes long enough to fill 60 litre tanks, I'd hate to have to wait at normal pump speeds to fill the 600 litre (or whatever they are) tanks the lorries use.
Side note 2 - don't know if it's just the local residents being a bit more dimwitted of late, but I've noticed a resurgence in cars travelling down the road with filler cap / door wide open. Suspect we had a brief lull when locking caps came in to stop siphoning and now cars tend to include the tank flap in the central locking they've done away with individual locks on the filler caps and so you can once again start the car without realising your keys are still attached to the filler cap?
