Has anyone ever been arrested for smoking inside a "No Smoking" restaurant?

This law, in my state, is very, very weak. its not a criminal offense to smoke in a restaurant in Tennessee, but rather a civil offense. when this law was first enacted, our Governor was about to hire x number of civillians to go out and write citations. since the budget crunch hit Tennessee, this idea was forgotten. so, the civil law goes unenforced. the fine is only $2.00. Question: a $2.00 fine does not seem like much of a deterrent for people not to smoke in restaurants and there is no enforcement, SO, why are people NOT breaking this law and lighting up after a meal?
