I have to deal with the overwhelming perfume at work, it is so strong that after an hour or two I am sick to my stomach, and have a headache. I keep an odor neutralizer on my desk to help (and it does) but everytime this person walks by my desk I have to hold my breath.
My daughters have learned not to wear perfume, or scented lotions when they come home, they are considerate enough, but shopping is a horrible experience for me as well.
