Ever the idea man, I've come up with something that will benefit both wearers of scents and the unscented alike. It's a device one could wear on one's person that would give off some sort of warning signal if the wearer was wearing too much scent. Something memorable, like, oh I don't know, a taser to the nether regions. Or possibly a light mist of pepper spray into the ol' eyeballs. Of course it would have to have a security setting, so that if anyone tampered with the device it would unleash a constant shock until a technician arrives in 2-3 business days.
I'm not sure what to call it. "Anti-Stink-O-Meter" is just too cumbersome. "Serves You Right You Rat Bastard! Why Don't You Try Bathing With Water Instead of Perfume/After-Shave?" even more so. Maybe "Stench-B-Gone". I guess it doesn't really matter what they're called. People aren't going to buy them for themselves, and they're installed with a nail gun. (In my world, they are.)
Can you tell I had to deal with people today?
