Have you noticed that not everyone cares too much about the odor they emit?
Do you recoil at times when you walk past an apparently pleasant-looking person, as the olfactory experience they incite might call for fumigation?
I confess that one place where this might be an extreme problem is the Apple store.
Apple stores are so full of humanity at most times of the day. One has to squeeze through, in order to venerate a product or two.
