The many TikTok-ers among us love making Duets. So Burger King in Brazil and DAVID São Paulo gave these young, creative people a way to use a Duet to order food from their local Burger King. The brand created one half of a Duet and posted it on its own TikTok channel, and invited people to complete the Duet with their own half. When they did, and included the hashtag #DuetoBK on their video, the brand contacted them immediately to fulfill their order. A fun, engaging way for people to get their Burger King, their way.
