After he�s had his ciggy once he has shut up shop, the smoke he produces will linger (even more than the pee in the swimming pool, where the water is constantly being cleaned). It will still be there at the start of the next session when his customers and staff arrive.
Unfortunately, if allowed, this will be the thin end of the wedge because, as we have seen from this question, people always stretch any boundaries that are imposed to see where the limit really is. The next thing will be that family and visiting friends will be lighting up in the bar outside opening hours, and so it goes on.
