Burger King's Free Coke in Can

As a citizen who leave in a country with a high paying tax, we ought to love freebies and discounts. (who wouldn't love that?) As a mom I'm only being practical and glad that some of the things I purchased has/have rewards. Now I'm gonna share with you Burger King's Promo. We always dine in BK. They always have a promo and its written in their receipt with the instructions on how to claim it. (that's why you should always check on your receipt!!) It was only now that I decided to read it carefully. Before, their promo is a FREE upsize coke and fries when you order a Whooper Meal (that I never did claim because I'm too lazy to do the steps how to claim it). Then Last Saturday I decided to complete the step. I wasnt able to read the whole promo because for all I know it's a free upsize but surprisingly after completing the survey the manager of the branch hand me a FREE Coke in Can. Glad the manager is nice and helped me with the steps. Still have receipts from them and will answer more survey to claim my Free Coke.
