Why Does This Bus Stop Smell Like Cookies?

At last, bus shelters will have a pleasant smell. Or so says the California Milk Processor Board, which plans to embed the alluring scent of cookies into outdoor milk ads in San Francisco. Commuters would take a whiff and, in theory, scamper off to buy some milk. And damn my sinuses if this sort of thing isn’t becoming commonplace. The San Francisco Gate mentions “marketing blitzes” such as “the ‘new car’ aroma at auto dealerships, ‘fresh-brewed coffee’ smells in convenience stores and ‘rose scents’ for florists,” none of which has yet met my persnickety olfaction.
