This is her job. How hard would it be for the other woman to tone down the perfume? I know I would if my perfume was causing someone else distress.
I use to love to wear perfume. In fact, White Shoulders was my very favorite. But as I grew older, the more allergic I am to it. I can be sick for weeks just from going down the candle aisle at a store. I have no idea why I grew allergic to it over the years but lots of people I have talked with about it have said the same thing. It did not bother them when they were younger but it does now. When we are having choir practice, people will stop practice to remind people not to wear perfume. It is not good for singers as well as others to have throat and ear problems due to a smell that is not necessary all of the time.
