We can contain radiation, we can contain liquid helium, surely we can contain cigarette smoke. We don't need staff! We can be served remotely our money can be taken electronically. The venue can have it's air filtered overnight before the cleaners come in!
They could even wear suits and respirators as with asbestos! Yes, this would cost, so we would have to pay more for our beer.
Try thinking outside the box instead of just attacking smokers, believe it or not we are people too! We also have feelings!
