I never did much office work because I mostly worked in construction but the smokers get more "acceptable breaks" than non smokers and this is a bit unfair if you ask me. If someone left their post as frequently as smokers do in order to do something else like say, spend the same amount of time it takes to smoke playing a GameBoy or something like that, they would be reprimanded for it.
I can't even imagine call center work buddy. I feel your pain :)
