McDondald's in Nigel ran out of Big Mac meals!

McDonald's in Nigel ran out of Big Mac burgers, how ridiculous is that. I ordered my regular Big Mac meal at the drive-thru and gave them my code obtained from their useless App to upsize for free to a medium Big Mac meal, only to be told that they are out of stock on Big Mac meals. Even the so called reward points on this stupid App does not work, I have made 3 qualifying purchases already for which I received absolutely no points at all. What a waste of time to even try and utilize this App. They can just as well close the restaurant in Nigel, how do you run out of your most popular burger meal? Just does not make sense. I think I will stop supporting McDonald's restaurants for quite a while!
