Check for oddities, like all the civil servants being sacks of leeches shaped like humans. Or all the parking meters change position each night, slowly forming the subtle orbital patterns of an ancient babylonian incantation.

If there's a rule that everyone breaks, then anyone who breaks it doesn't stand out. In fact, people who try to call out other people for breaking it get called names for being holier-than-thou or a wuss or something analogous. Anyone who decides to follow the rule gets taken advantage of by people who break it, so they don't feel bad about breaking it themselves. Even if it harms other people, those other people are rule-breakers so it's still a fair situation.
