Burger King customers who receive a cold, incorrectly prepared or disappointing Whopper can now have it remade immediately and claim another burger free for their next visit.
The fast-food chain introduced its new 'Whopper Guarantee' to address frequent complaints about food temperature, order accuracy and customisation. The promotion is available at participating US restaurants until 31 August 2026, covering peak summer travel season. Customers must report the problem during their visit and complete a QR-code redemption process to receive the free burger. Several restrictions apply.
