Aside from the usual ones (jaywalking in particular wouldn't be atypical), I technically broke every rule in school at least once (all except two exactly once). I say "technically" because the rule-enforcement format at my school tempted classmates to snitch on each other for the smallest things. Like, did I walk into class two seconds after the bell? Did I laugh too loudly at something a classmate did that wasn't supposed to get ridicule? Did I wear the wrong socks for my uniform (and yes it was the same uniform as you)? Anything like these would get you in trouble.
It was rumored that the moment I broke a rule more than once, I would face something more serious, like mandatory appointments or something. There were only two I broke twice. One of them was because, on one April Fool's Day, everyone wanted to pull one of those cheesy end-of-the-year-style pranks where everyone shows up in the uniform of another school, but people didn't get the memo on what uniform it was going to be, so when everyone came in that day, it looked like comic-con, and I went with a friend's (who went to another school with another uniform). The teachers just shook their head about that. The other rule I broke twice was exam cheating; first time got me caught, second time allowed me to graduate (and I didn't get caught for that, though I fear what would happen if it got out).
My most severe punishment from school and the only one I remember getting me an in-school suspension was when they asked me to help write the yearbook, and I got to the part where everyone played the "most likely to" game, and we had an entry put in as a form of dark humor (disclaimer, DON'T do this, I admit it currently but I would neither encourage it nor use the same humor today even though the same thing has happened before... also don't harm innocent people). I was in the in-school suspension for a day where they add suspenders to your uniform as their own cheesy cruel joke (their chosen mark of someone being suspended). Because the protocol works based on punishment escalation, any rule after that would've gotten me removed from the school, so it's a good thing they didn't catch me cheating on that test.
I'll start with fellow followers of Christ and say a lot of the ones I've met aren't as easygoing as would be stereotypical. Now you might read the Bible (or the Book of Mormon, or the Book of Hagoth; I have 'em all) and think "hey that person over there is famous for their devotion, I'm going to strike a friendship" and then realize it's a lot closer to "stepping on eggshells" than you might think. Points to other Hagothists/Mormons though as they actually have been understanding people. Gossip, hate, whatever you want to call it, I'm no stranger to bearing witness to it, and you often wonder "wait, why are they involved in this". It's also complicated because, by the same token, they have positives like what we might call tolerance towards the LGBT, so there are other dimensions to it.
Technically not a "religion" per se, but the atheist situation strikes me as odd. It often seems like their attitude towards adherence to God is second-hand because what they'll say about God they'll never say about government, or they'll do it rarely. Everything to most of them considered "questionable" or "concerning" is only "questionable" or "concerning" when it involves divine authority. I have joked before that if climate change or Marxism was in the Bible, nobody would believe them.
I also noticed a lot of Buddhists couldn't quote sutras from the Tripitaka or don't follow them to an extent where the individuals are Buddhist-esque enough to rely on to be peaceful towards your dilemmas, almost as if it's for show. Heck, I'm not a Buddhist yet can quote sutras that aren't in the Tripitaka (because not all of them made into the final edition).
