the pub i work in was heaving NYE and no-one was bothered about going outside for a ciggie, trade did drop off for a while, but since we've had new owners its picked up and is rammed most nights and i reckon 70% of the customers are smokers. mind you there is a pretty good covered and heated smoking area, that might have something to do with it.
i smoke but i prefer it since the ban, i can go in do a shift and not come home reeking of fags, nor do i have to put up with smokers at the bar esp cigar smoke.
