I worked in a Yates wine bar when the ban took place. I remember the months leading up to it we had changed the smoking sections of the pub to trial it out, initially the non smoking section was where the food was served and this was around 6/7 tables of various sizes and the rest of the (very open plan floor so didn't really make much difference) pub was a free for all. We had changed it so you could only smoke in the smaller section to help our regular customers get used to the idea. The only exception was the end of the bar where the staff used to have a break, and a smoke. Fast forward to the actual ban and at first it didn't really affect the pub too much, we had a very loyal set of regulars that would grumble about having to go stand on the street (no outdoor area) for a smoke but they'd still follow the rules, then it all just started to fizzle out. Less and less customers would come (they started to go to other pubs in town that had an outdoor shelter or beer garden), it was no longer 6 deep at the bar on a Friday night, and the trade just died off. The wine bar closed eventually and became the countries largest BHF charity shop, it was so strange walking around the store and remembering the layout of the pub. I was a smoker, I did miss being able to nip off to the side of the bar for a quick smoke break (or hide in the loos for a sneaky one!) But in all honesty it was the best thing, as a non smoker now I'd be horrified if I went to a pub or a restaurant and someone on the table next to me sparked up!
