I remember they passed a law here in MA saying all bars and restaurants had to build these high priced enclosed ventilation systems in order to allow smoking indoors.
And most places built these things and spent 10's of thousands of dollars doing so.
Within a year MA said no smoking at all even in private clubs
There was no classaction suite by the bars and restaurants who lost thousands of dollars to reclaim the money which the state had forced them to spend, we would have no chance at all, not even worth thinking about
