I live in the state of Florida (USA) and smoking has been ban in public enclosed places for about 4 years, this includes bars, & restraunts.
I am not a smoker; I agree that smoking should be ban in public & goverment facilities,

however I also believe the owner of a private business should be free to make the call as to allow or dis-allow smoking in their establishment.
If a private business owner wants to allow smoking they should be FREE to do so as long as it is clearly posted at the door. If a customer has a problem with this policy then they are also FREE to go else where.
