Here's a nifty guerrilla promotion put together by Dutch customs at Schiphol Airport to remind passengers to double-check their luggage for items that have to be declared before leaving the country. The marketing agency in charge of this campaign decided to go guerrilla by setting up a fake suitcase that had an alligator tail sticking out of it. A large sticker on the luggage questioned, "Something to declare? Please go to the red channel [line]."
Travelers are usually distracted and hurried at airports, so it's difficult to catch their attention. However, there's nothing quite like an alligator tail sticking out of luggage on the baggage return belt to stop someone dead in people dead in their tracks and get them to pay attention! Another fine example of the hypnotic power of successful guerrilla promotions.
