Whatever the actual number of petrol stations without fuel, and the actual shortage, which is clearly extensive, Brexit has caused the current problem. By rapidly speeding up an issue, of shortage of labour and in particular drivers, to a point it has become unmanageable. Which was warned of consistently. Labour, as well as goods and materials, in many other sectors as well.
I actually agree with your repeated and ongoing point, on this thread getting heavily focused on brexit arguements. As much as I'm all for leavers seeing these I told you sos and maybe even considering the outcomes, ultimately I'm on this thread for videos of muppets trying to fill extra pertol into condoms and what not.
What I don't agree with, is arguing that Brexit has nothing to do with it. Particularly when other contributing reasons get discussed and that doesn't seem to be at odds with the topic of the thread.
Saying Brexit hasn't caused this, and the other big issues we have seen all year in all sectors, is like saying shooting yourself in the foot hasn't caused your limp because that urinary infection you had some time ago was already making you walk a little sideyways.
