I haven't been to BK in a while, but during grad school the back of every receipt asked you to call a number, complete a survey, write down a code, and redeem the receipt for a free Whopper. The code consisted of two letters corresponding to the month (the key to which was easily found online) and four digits (which I just randomized). The kicker was that BK would give you the free Whopper...and a receipt for the free Whopper. And the cycle continues. |
