It is not the same setup. A local ice cream parlor isn't making ice cream on the fly. They are scooping it from premade buckets stored in special freezer case

  Soft serve machines that take liquid mix are in nearly every single establishment that offers some form of Ice cream. This isn't special technology. As other's have pointed out, McDonalds, or their franchises, wanted to eliminate the couple hours of labor usually required to clean those machines daily, and so developed their own mix, and Taylor made special machines that would "self clean" to support it. For safety reasons (probably), those machines lock themselves down if anything goes off the sanitized happy path, and only super expensive Taylor techs have the requisite knowledge to get them back on track. McDonald's is alone in this struggle because they wanted to save $20 a day in wages. It's $350 per 15 minutes to fix the machines, so assuming it's just one button to fix them (it's not) it only has to break down less than once every 18ish days to pay off, but it doesn't scale well if the machines are less reliable than that.
