Now that the Dutch have banned smoking in bars, bar patrons have realized they can smell each other, and they don't like it. So a Dutch company, Rain Showtechniek, has created a machine that will create a fake tobacco smell. From The Telegraph:
"There is a need for a scent to mask the sweat and other unpleasant smells like stale beer," said Erwin van den Bergh, a spokesman for the company...
Unlike the real thing, the artificial tobacco smells do not have any health risks and does not linger in the hair or clothing of bar customers.
This might really be necessary, since I've noticed that deodorant seems to be less popular in Europe than it is in America.
