I've worked at a cleaning job where the smokers were allowed to go outside whenever. Some even went on a smoke break several times per hour. The nonsmokers like me on the other hand were reprimanded if we sat down and drank something outside of the scheduled break. I complained, but the boss was a smoker and just told me they need their smoke break but I don't need coffee.... One coworker whom I talked to about that even said they started smoking because of this and because the non-smokers were expected to work more and cover for the smokers on their cigarette breaks.
