True enough. One thing when you don't smoke is that, when you come back from a night playing in a smoky pub or wherever, you really do appreciate how much your clothes stink of stale smoke.

What I really hate is when people put down a cigarette to smoulder in an ash tray instead of stubbing it out - at least with smoke that's been through someone's lungs, the worst of it is filtered out by the time they exhale. Which is rough on their lungs, but makes it a bit less unpleasant for the bystanders.
