I guess for the foreseeable future UK will continue to blame all of its problems on EU, like 40 years old dude claiming that it's his parents fault since they didn't let him take dance classes. It's all his parents fault that he tries to meet the ends when living in a rundown neighbourhood instead of being world famous and rich dancer. Damn parents, it's totally not because of partying instead of studying.
You seem to be replying to arguments I didn't make. I haven't mentioned selling stuff to the EU anywhere nor does this topic have anything to do with that.
Brexit is excellent because the EU is a terrible political/constitutional project, but that has nothing to do with petrol stations or truckers. Indeed Brexit supporters aren't blaming the EU for this because it'd be a non-sequitur, it's the other way around: people loyal to EU ideology are blaming Brexit for it, without evidence actually and in ways that appear to be quite manipulative (e.g. deliberately lying to provoke a run on petrol then blaming that on Brexit).
BTW the attitude you display here is exactly one of the reasons leaving the EU was so important. I've never once encountered an EU fan who displays a friendly and cooperative attitude, or an understanding of why people voted to leave. It's always immense bitterness, stupid analogies and insults.
As a result, this will bring you the opportunity to do your own thing like all the outsiders out there, like produce and eat chlorinated chicken, put asbestos in kids toys if that's your thing but you will be required to prove that you are sending the un-chlorinated ones to EU. That's why you have checks and paperworks at the border, it's not to piss you off. Anything that's happening currently is the logical outcome of Brexit, it's not a conspiracy to make life hard for the British. We love UK and the British culture, that's why we are so sour about this "We are better than the EU" thingy. Seriously, besides some jokes and snarky comments, no one wishes bad things to the British people.
Anyway, so since you left, when do you expect to meet the friendly, cooperative people who don't insult you for expecting unreasonable things?
Where has anyone said "Britain is better than the EU"? Nowhere, that I can see.
When did anyone express incomprehension at the existence of border controls? Not here.
Has anyone said they want to put asbestos in children's toys? No, that's some sort of straw man.
Nonetheless, there is hardly a matter of principle here. The EU imposes very strict tariffs, border controls and various forms of market manipulation within its territory. There is a difference of scale, but not a huge one. The proximate issue here is that the social class of people who stand to lose out from Brexit saw an opportunity to both (a) stiff the workers leading to (b) more money whilst (c) scoring an ideological goal over their opponents, hence telling the press there were going to be imminent huge fuel shortages despite no actual change in the trucking situation ... thus neatly creating the problem they were warning about.
