As long they don't keep the "lowest price" the regular base price, this does have the potential to disrupt fast food purchasing habits. Imagine people always trying to game Wendys to see if they can get the burger cheaper, you'd theoretically see a sine wave develop over a month or so. Then that sine wave would translate laterally as time further progressed and people adapted to the shifting surge pricing. It also has just as much likelihood to ruin Wendy's sales, but time will tell.
