Ironically, in this case it's the nanny state telling the nanny local government not to be nannies to the individual.
I hope that smoking restaurants will in the near future be treated with the same disgust as a restraurant which openly allowed chewing tobacco and spitting. But since I don't own the restaurants, my only moral option is to choose not to patronize them, not threaten them with government violence if they don't do what I want them to.
