Well the question is why does McD franchising terms stipulate they have to buy a special model of the machine, but it seems that no other fast food places that use ice cream machines from the company have such a requirement.
I mean I guess there could be other reasons of features or quality or something, but it seems a bit strange. I mean, in the end, it's just McD machines that constantly break down, so if anything you would think HQ would want to improve this situation somehow, when it seems they are completely uninterested.
Maybe McDonald's has decided, their unique ice cream mix performs better in taste tests, or that it works better for McFlurries, or whatever... but the one downside is that it jams up machines much more frequently.
If you already anticipate that your ingredients are going to break machines quite often, and that you'll require a lot of repairs, it would benefit you to standardize on a single large-scale support contract rather than leaving it up to every independent operator for themselves. Kind of the same way taxi fleets usually mandate one single specific model of automobile despite thousands of independent medallion holders.
