Something I don't understand . . .

I recently have seen two offices that have signs that declare them to be Fragrance-Free Zones. That does not make sense to me, because:

1. even if you use no-added fragrance beauty and cleanliness products (soaps, deodorants, etc.), the products will still have some fragrance

2. in the buildings, the soap and other cleaning products have some smell

3. even if the people in the buildings used no products, people naturally produce fragrance (we usually want to use products with smell to cover up what nature provides)

OK, rant over.
