Here's an interesting street-level campaign from Ogilvy Brazil to fight drunk driving. Working with bars, the agency came up with a machine that spit out wildly inflated bar tabs, ambushing patrons with charges of up to $73,000 for the booze they just sucked down. Upon closer examination, the bills actually featured an itemized list of medical costs associated with a drunk-driving accident. The video case study below shows customers' reactions caught on hidden camera by Hungry Man's Paulo Gandra. Ogilvy Brazil is doing lots of this kind of stuff lately. Check out this recent campaign for Burger King, in which the agency photographed patrons waiting in line and printed their photos on Whopper wrappers—another way to personalize the "Have it your way" positioning.
