Restaurants in Belgium have been closed since March 12, but in the past few days, both McDonald's and Burger King have announced that they are opening up their drive-in outlets. 

To promote this to customers and whet their appetites ahead of the reopening, Burger King and agency Buzzman have posted images on social media of some of its sandwiches—but "censored" by placards so that customers don't get too excited before the drive-ins resume on April 23. 

"Drive reopening soon. In the meantime, let's avoid any frustration" says one placard, covering up the image of a Whopper. "No really. There's no point hurting yourself," says another. 

Buzzman's stunts for Burger King in lockdown have also included the Quarantine Burger in France, which gave customers helpful pointers on how to assemble a Whopper at home, and a homeschool focused app getting students to do math problems in return for Whoppers. Worldwide, the brand's efforts have included its Stay Home of the Whopper campaign, via FCB New York, which encourages fans of the brand to be "couch patatriots."
