You poor thing; I can relate. I work in a cubicle farm, and there was this one particular girl whose feet were wretched!! And she wore sandals that made it even worse.. Luckily she is off of our line now.. I feel bad for whoever has her on their team.
Does your POE have an anonymous tip/help line? Mine does; it seems worth a call to at least inform them. This way, they act as a moderator in between you and the offender.. and you have a "clean nose" by doing it anonymously.
Spray aerosols seem like a great idea in the meantime! Just don't set off any sprinkler systems with your candles! Then again, that might wash the smell away.. a small desk fan is a necessity in my office. I also work with an awesomely outspoken lady who will shame anyone who comes in with excessive onions, etc..
