Barmaid - I have asthma and a severe reaction to cigarette smoke, to such a degree that I hadn't been to a pub for years before the ban and I have to keep my windows closed when my next door neighbours are outside smoking.
It causes my tonsils to swell alarmingly, and my bronchi become extremely inflamed which my inhalers don't relieve.
I have been hospitalised twice directly from other peoples cigarette smoke. Yes, that is my problem and not yours, but maybe it is that woman's too.
