Update 27th Sep 2021
Petrol & Food - South England
My experience yesterday and this morning. If anyone is interested
No food shortages. Everywhere seems to be fully stocked.
Petrol stations are open, diesel is still in abundance. E10 unleaded petrol has gone completely. E5 super unleaded is available in most garages, but is in short supply in general.
I paid £1.43 / litre for super unleaded at a Tesco garage.
Long queues to get fuel (20 minutes to one hour), most garages have attendants directing the flow of traffic.
