The best ideas are often the most simple. This fantastic ad to discourage drink driving is a case in point. Used by the Hotel Marriott in India for patrons of its popular nightclub Enigma, this ‘personal stamp ad’ listing the phone number of the local cab company proved to be so effective the idea is now being taken up by the Mumbai police and is being adopted by other clubs.

Awesome idea.

brilliant-- why aren't we doing this here-- -it should be law
