According to this article anyways. Here's a blurb about the buskers: "The city’s business license officials have also been more diligent about citing buskers who demand money for photos. If buskers accept tips, that’s permissible. If they demand payment and are aggressive about it, they can be cited for failure to have a business license and fined up to $500. A street performer using the name “Misty Sins,” who wears a devilish, barely-there costume and covers her breasts with a large red fan, is careful not to demand money, but for a tip she will remove the fan and show her breasts covered only in pasties. She said a dozen characters were cited last weekend. “They should give a warning the first time,” she said indignantly. “How are they supposed to pay a $500 fine?” Performers are being asked for identification and that’s how some of the outstanding warrants are being found."
