Oh, and clarification, she was here six hours, not ten. And I am guessing she didn't say anything before we were done for the day so we would at least get a full day's work done without my freaking out or getting upset (I did neither--at least not in front of her).
And to aw, no, I don't necessarily "expect" anyone to work around smoke. But many people DO still smoke in their homes (and I'm not inclined to stop right now), so it would be nice if service providers noted those limitations on their websites, just as they put in requests to put pets outside (a request she has noted on her website). I'm not angry with her, just feeling a bit frustrated.
