You're actually wrong, C.
The French custom unions have been working to rule to show the country isn't ready for a no deal (and to consequently demand a massive wage rise and loads more jobs.)
They searched every bag for the Eurostar, meaning there were 6 hr delays and queues coming out the Gare du Nord.
Then they also started asking every vehicle at Calais to show them the docs and checked it matched the number plate. Nothing more. But this led to huge tailbacks.
This is why I didn't buy my usual ten quid coach ticket back and spent a nifty or more flying from CdG. (Some small new terminal, 3. Don't remember that from my St Martin days. Was 2F for long-haul back then.)
And there, despite arriving over 2 hrs before hand, they had to round those of us still queuing a T-20mins when the gates were meant to close and get us through security.
Flight delayed for 40 mins.
So they have been doing this.
I don't know about cheese, but assuming WES is accurately reporting what his fromage-wallah was saying*, then given what I experienced in March, I have no reason to doubt him. The Customs Unions were doing this as part of a co-ordinated action.
And it's not illegal. AFAIK. But I'm not an expert on those things. But it certainly wasn't according to UK and Fr papers in terms of the GdN and Calais checks.
*Ask him who scored the sexiest goal vs Napoli to see if he can speak the truth.
The bottom line is that you can't interfere with goods travelling between two EU countries, g. What those whacky frogs choose to get up to is their business, but they're in breach of some fúcking convention or treaty or somesuch.
****s.
I'm off to France in June for a birthday party and the bástards at BA are rushing me over 200 quid per head. In economy, for all love. Economy!
Don't shoot the messenger, C.
I know what they were doing at CdG and GdN in March. And assuming the cheese checkers are part of the same union, I'd easily believe they're doing it too.
Any customs man can check anything they want. Normally they just check the odd thing. But if Jean-Pierre Douanier wants to check the contents of every single package going to the good old Royaume-Uni, then he's allowed to.
I know it's confusing you that a froggie union member is actually doing his job properly instead of going on strike, but this is what Macron's done to the country.
I foresee a career for myself as a swashbuckling cheese-runner, sailing the Dover straits with my fast and weatherly three-masted sloop packed to the gunwhales with Boursin and bound for the South Coast with a damned Xebec full of frog Excisemen in my wake.
