Imagine being in a rush, or even on time to get to the airport, with all the excitement of a holiday years in the planning...months of anticipation after a hellish couple of years...weeks of uncertainty as to what whim Boris will shut something down...and days jumping through hoops and paying through the nose to get all your tests done....
...And these lot block your path to the airport (they are at the Heathrow junction of the M25). Makes me want to go full Spymaster tbh.
I'd be amazed if this wasn't some sort of an undercover infiltrator organising it to ensure public opinion is against them
