I'm guessing you're from UK? Travelling to UK always means a passport check and usually answering a few questions. This is pretty much every single time.
If I go to Indonesia for which I need a Visa on arrival, they asked me zero questions, nor said anything. I handed them the money, they gave the visa (etc), done.
For many countries I don't need a Visa for. Saying EU is freedom of movement, but then narrowly defining this something else is moving goal posts.
I have various foreign colleagues (non EU). They need a Visa to go to the UK. UK being part of EU or not does not make that much of a difference for them at all.
The effect is whether you can easily work in another EU country. But that is just one part of "freedom of movement".
