I'm from Slovenia as well and get asked to show my ID and vaccination slip regularly.

If I understand correctly, one of the pandemic laws requires them to verify, but the Information Commissioner's Office has countered that with one of their classic "well yes, but actually no" opinions saying that they're not actually allowed to demand that kind of information. What "demand" means here, of course, doesn't seem to be defined well, so I'm guessing they're still allowed to refuse service if you don't show them some proof.

Or maybe all of that has changed in the 20h since I was last at a bar - the speed at which the current government is making seemingly entirely random changes to the covid rules is genuinely impressive.
