I'm a smoker and I damned well enjoy it.
What I have noticed over the years is that after a few hours deprivation I can detect burning nicotine at 500 yards.
Had not occured to me - but you are right - ground now seems smoke free. I didn't feel the urge for a faggly at all - so no smoky wafts can have been reaching me nostrils.
For the record - I agree it is ludicrous to allow smoking in any sort of enclosed public space and have never knowingly smoked in an enclosed area where it is banned. So I hate the monkeys who break the rules too because they make it 100 times more difficult for me to just enjoy the game without thinking how long it is to my next ciggy.
I exited the spirals thinking only about the game when huge waft of luverly smoke had me fumbling for me fags.
