a few years ago, I think it was about 10 years ago, we had a fuel "protest" in the UK, the refineries in the south of England were blocked off and nothing was getting in or out. food in the shops was not getting replaced and the shelves were getting empty, bread and milk were the first to go. petrol filling stations ran out of fuel within 24-48 hours and people were panicking. the stupid thing about this is: 1, it only lasted 1 week and 2, it was announced well in advance so nobody could say they weren't warned. I had a full tank of fuel(I always fill up when it gets to half....old prepper trick!) and we got in extra supplies before the protests began, and we just sat back and waited.
