LONDON, ENGLAND - SEPTEMBER 25: Out of service signs on fuel pumps at a Shell garage which is out of all fuel on September 25, 2021 in Grove Park, London, United Kingdom. BP and Esso have announced that its ability to transport fuel from refineries to its branded petrol station forecourts is being impacted by the ongoing shortage of HGV drivers and as a result, it will be rationing deliveries to ensure continuity of supply.
