A few days ago, Burger King Japan offered a promotion for unlimited burger and fries. However, one cannot simply get it in a blink of an eye.
To take advantage of the promotion, a customer had to order a “black burger meal” and finish it all and present the receipt and wrapper at the counter. Only then can he or she take advantage of the eat-all-you-can special. Also, the promotion lasts for only 30 minutes after you buy your burger meal.
It’s a sneaky technique, but I’m pretty sure many customers enjoyed the treat.
The promo was to celebrate the fifth year return anniversary of Burger King in Japan since all BK chains were closed in 2001 and were reopened back in 2007.
