If it is not broken, do not fix it. This is not the case for McDonald’s ice-cream machines. They seem to be broken continuously. Roughly ten percent of McFlurry or McSundae ice-cream machines are not working each day at McDonald’s. Software developer Rashiq Zahid uses the interface of McDonald’s ordering API to check if their ice cream machine is working. It is assumed if no orders are made, it is safe to conclude the machines are not working. Rashiq’s app is called McBroken.
