> It seems like McDonald's locked onto one machine for a very long period of time. Other fastfood chains may have moved on from that machine after they noticed problems with it (or otherwise passed on it). It was confusing that the video repeatedly mentions other chains don't have the problem despite supposedly using the same machine (but is it actually the same machine, or is it merely a similar machine). Indeed - considering how much effort they spent on the details, they could have tried to obtain what the rival outlets were doing different considering they also use the same manufacturer and don't have same issues E.g. the model details on rival outlets to see if this issue was not affecting other Taylor models. >> One of Wendy's employees says that they wash the machine every night. Are McDonald's not doing this? > McDonald's is doing that as well and that's where the machines are commonly failing. The employees come in the next morning after running the clean cycle overnight and find that it failed. So they have to go through a four hour process from there forward and it might fail again before that is properly completed, and so the cycle resets. Again, this is the same point - if both outlets are doing the washing, then why is it not affecting Wendy's? Difference in model or process of washing is not same or Wendy's have added additional instructions to deal with such issues e.g. not overfill the mixture etc? Basically, the missing comparison is an obvious omission from, what is otherwise, a great video.
