In Florida, the cops are employed to invent new ways of making arrests, so having the law on your side is almost no protection.
Further, in Florida, I believe the law only covers you at your place of business, but I do not think that the law could legally extinguish a person's right to let his invitees conduct themselves in a fashion approved by the owner, especially if the owner erects a sign explicitly revoking the implied license of the police to enter.
Still, it's not wise to tempt the cops in Florida. They're mean; they're out for blood, and they lie. No business owner would dare cross them. Florida's not really America. If you want to OC, find a real state.
