McDonald's distributed coupons worth a Grand Big Mac at a point on Avenida Paulista, with the condition that the public participate in the “Your Hunger Will Scream Louder” game”. To receive the coupon, participants should shout into the microphone installed on the MUB the phrase “The Grand Big Mac is Back” as loud and high as they could. After the interaction, the coupon was sent directly to the registered cell phone via MUB.
