We managed to get petrol this morning at Morrisons. As mentioned above, the staff were fair and organised and a chap who attempted to queue jump and refused to budge only moved and joined the end of the queue, when they told him he would be refused petrol at the pumps. Anyhow we were there around about an hour. We did try the two garages by Goose Green before heading to Morrisons and both had "no petrol" signs up. Good luck - I keep thinking of the original Mad Max film.
