Dover problems..am I being cynical?

I just managed to miss the tail end of the queue for Dover on Satuday night as I went in to catch the train but it got me thinking as to why the only border with queues due to so called heightened security is Calais and why did the French authorities suddenly find themselves short of staff on the first weekend of the British summer holidays at the busiest port and why when I came back into France from Belgium last night there were no so called heightened security checks at the France/Belgium border and no reports of the same on any other borders.
I drove straight off the shuttle and out of the terminal without having to showing my passport so wondering if the problems at Dover over the weekend were our first Brexit beating or am I just being cynical??

Your not cynical just British

They were messing around on the Belgium border yesterday, I say messing around as I didn’t see much in the way of checks, they were taking all vehicles off the motorway in both directions round a roundabout and back on, while police and soldiers looked on, and it was causing some serious tailbacks. What with that and the motorway being closed before that due to an accident, it took me longer to get out of France than it did to get out of Dover.

They’ve been doing this in both directions for weeks. Although everytime I’ve been through there’s been no police or soldiers there. I put it down to the French being French and them wanting to scrap the Le touquet agreement.
