Cigarettes & Gum
I think that cigarette companies should develop their own gum or breath freshener that they can sell with their cigarettes as a package deal. It's really irritating when coworkers who smoke come asking me for gum or mints. If they're smokers, I think they should be well prepared with their own supply of breath fresheners. Maybe cigarettes could come with a piece of gum, the way baseball cards do.
All in the name of making our world smell just a little better.
