I remember thinking that once smokers got kicked outside to smoke it wouldn't be long before someone thought of putting ads on the ashcans many bars use -- you know the types, long skinny necks with a couple of holes up top that you can push your butts into. I can't say I ever paid a single moment's attention to any ad I've seen attached to them.
But I'm pretty sure if I was bumming a light in London, these ashbins
would defintely stop me in my tracks. (Not to say I'd take heed. If those New York State Smokers Quitline
PSAs haven't dented my thick skull, I'm not sure what will.)
