I remember there were ashtrays right up until the ban practically in the offices I worked. I am trying to remember how many years ago, I think roughly 20 years ago maybe? It was on its way out but was till a thing, especially if you had to work the weekend. It is crazy to think of how far we have come. As someone said recently, we wouldn't vote to allow smoking indoors again. This can only show how good a decision it was despite the militant lobbyists and the like trying to tell us that such freedom curtailing was the end fo the world!
My place got rid of their shelter of shame and imposed a smoking ban on the immediate area around the office. It has kinda backfired as the diehard smokers now walk further afield to smoke before coming back and spend a substantial amount of time away from their desks!
