The lesson I would take from this is to not honestly answer the office busy bodies questions when they ask. It's non of their business, just tell them you were'nt doing anything, hide your ecig, and deny any inquirys from the boss. Then of course find out the actual policy and stop using your ecig on the premises if necessary. Being fired for this kind of thing is ludicrous, it's not a wonder why some people get fired and return to do bad things when screwed over in this manner. It's also a good bet that those who would narc you out are the HVPTA types, I wonder if they have any office supplies at home.
