Good luck with your private meeting with your manager today, Sinsull. As others have said, you are NOT being unreasonable... but since your manager already has been, I have much doubt as to whether she will suddenly do a 180 and magically become reasonable.

Her having asked you (sarcastically??) whether it "really" bothered you before lighting up in the room, having received a negative response from you, and then blatantly doing what she knew would make you feel more ill (not to mention that she knew it was against the company rules) is, to me, reprehensible. IMO she should be reported to upper management, no matter how short a time you've been with the company. Who knows how many other complaints have been logged against her before you got there -- yours may be the straw that breaks the Camel's back.

As others say, be prepared to document future offenses from this manager -- not just the smoking but other instances of her disregard for company policy and the well-being of those she manages. Perhaps you should get one of those smoke zappers and get a camera-phone recording of it zapping and snapping at your desk while the plume of smoke rises from the other side of the partition.

Or perhaps, next time her smoke makes your nose run, you could use papers from her in-box as a Kleenex. Just a thought.
