It seems like you didn't bother to watch the video, but used the OP synopsis as an accurate distillation of the investigation... which it isn't. McDonalds (purportedly) have to use an inferior machine. This machine is used by many other franchises, including Wendy's, but the UX has been specifically throttled in the McDonalds mandated model such that the error messages are opaque. So much so, that when a newer version was rolled out, one of the techs posted a video wondering if anyone else noticed the error messages were getting worse (and the video was promptly taken down). Thus training becomes much more difficult when error messages are in Eldritch screeches instead of plain English, like every other model. I'm not sure if you've worked at McDonalds (you've never specifically stated in any comment) and you've never specified when. Is it possible things are different now to when (or whichever franchise) you worked?
