For the record, I'm quite a heavy (well 14 stone) smoker, and I have absolutely no problem at all with non-smoking venues. It's what the Great Outdoors was invented for. In fact I don't even smoke in my own house (can't stand the smell, as it 'appens).

The effects of cigarette smoke on others are so obvious that it would be curmudgeonly and selfish to even think of objecting. So let that be a lesson to you.
