Heh, it's funny the stuff I wouldn't use if not required to for work: fragrance, conditioner, moisturizer, the sheer amount of cosmetics, underwear... ;)
Though you should see the way my coworkers apply perfume, spray a large cloud in front of self and then walk into it, then several applications to the crotch area. If I leave a bottle out on a counter I can be sure of 20% of it being gone by the end of shift.
