I've followed the rules throughout and have found it annoying when people have took the piss. However, some people are going over the top.
I was walking through my local park today. Only a fairly small park and there wasn't many people there at all and it was all distanced. The police were walking through, presumably to make sure people were following the rules. I was on my daily walk and i'd seen these same officers half an hour ago coming out of another park. That's fine but as they were walking through an elderly couple made a beeline for them and starting going crazy, demanding they deal with this family or group, whatever they were, that were 'breaking the rules'. I was only walking past, so I didn't hear the whole thing, but i've no idea what rule they would have been breaking. It was a group of 5 people (on the other side of the park) and they were just kicking a ball around. The officers were trying to calm them. It just seemed bizarre to me and this couple were going completely over the top.
Then I read another story today about just how many calls the police are still fielding from the public. It's understandable if it's a clear breach, but it seems the bulk of these complaints are just very petty.
People are going to drive themselves mad seeing people mixing more as things open up. That was just an eye opener to see it in front of me.
