This is a taking of PRIVATE PROPERTY, only the owner of the property can decide on a smoking policy. Another example of Socialism at work.
The state mandates sprinklers, handicapped access, restroom design, inspects the kitchen, verifies the content of the menu, licenses the liquor and beer sales, regulates how many customers can be in the restaurant at one time, regulates the hours it can be open and what it can serve at what hour, assesses the wait-staff a presumed tips-income and helps design the parking lot.
Now, what was your concern?
Try telling that to the lawmakers and the Partnership for a Tobacco Free Everything. Ugh!
