I don’t get it. Why can’t bars and pubs display simple sign at their entrance that declares the establishment smoking or non-smoking? If the sign says non-smoking and somebody lights up, go ahead and fine patron and pub. If the sign says smoking, then let people smoke. I mean, bars can keep you out for not wearing the right clothes (and that’s happened to me plenty of times!) – they should be able to decide whether they want smoking or non-smoking customers.
