You spot a cute guy or girl at the mall who you don't know. You want to go and flirt with them, but if you're at a mall in Roseville, CA, you better keep it to simple winking. If you open your mouth, you could get in trouble.
The largest mall in Northern California, called the Galleria, banned strangers from talking about anything besides the mall itself.
The mall's rule does have some exceptions: If you already know the person who you're talking to then you're free to chat about almost anything. But if you're strangers, you must have approval from security to talk about topics not related to the mall and it can only be a conversation between two people in a small designated area.
Sounds pretty absurd, right? A California court of appeals thought so, too, and shot down the mall's argument that they were providing an environment where shoppers wouldn't be bothered by other people. Judge Tani Cantil-Sakauye of Sacramento stated that "providing a 'stress-free shopping atmosphere' for patrons is not a compelling interest compared to the free speech rights of other individuals at the mall."
