Because sometimes they make mistakes when they predict the future. Its possible that the crystal ball was fogging up, or the Ouija board wasn't able to make contact with the responsible Arby's spirit representative. Even a freak tarot shuffling error could be to blame. We may never know for certain what caused this tragedy.

Who knew that heavily promoted specials might run out faster than other menu items?
