Most UK pumps have disposable single use gloves there for you to use, i always keep a few in the door side pocket just incase there is none, usually at Asda the pump nozel is just as clean as the petrol one, different story though if you go to a truck stop, ther you will find much more spilled on the ground and the nozel here in the UK will not fit the filler as the flow is too great for the tank breather, but who wants 100litres in 60 seconds!!.
