I remember my first professional job in 2008 and noticing the lifts in the building had ashtrays in them. I couldn't fathom smoking in such a confined space with others!
I suspect smoking was banned in the lifts but, much like the ashtrays that still exist in airplane bathrooms, it is better that one exists for rule breakers than a fire is started because someone decides to drop the butt on the carpet and stamp it out.
