There is evidence that highest concentrations of second hand smoke are dangerous to a significant % of the population and that most do not want to be in any noticeable level of smoke. Seems fair that a public house should do something but the ban was just vindictive. The ceiling mounted extraction systems were just the job imho..

There is actually no evidence that second-hand smoke is dangerous...
