Hope you enjoyed your time in Ireland. I am just in from the pub (my bi-annual visit}, and am delighted that I do not reek of stale tobacco. Most pubs here that have the space have built small open air extensions so that smokers can go and smoke without getting wet.
Since the ban has been introduced, smoking rates have dropped, and that surely is a good thing. I am an ex smoker myself, and am in favour of the ban, from a health and safety point of view. It just isn't fair to expect non-smokers to work in a smoking environment
