There's always someone who ruins a good thing for everyone.
The law's unfortunately like that too. Many rules are created because certain people just couldn't stop themselves from being scumbags or taking advantage of a good situation. Like did you know that it's illegal in Alabama to wear a fake mustache that causes laughter in church? What's the backstory behind the comedic genius who's responsible for that ruling?
The same goes for restaurants, parks, or any kind of establishment. You ever see a weird sign with an obscure rule or a warning against doing something that should be common sense? Don't you just wish you could talk to whoever put the sign up to learn why they were forced to do so? Some signs just leave us with burning questions.
