There is none, but "broken McDonald's ice cream machine" is a whole category of meme. So people start wondering my McDonald's is so plagued by machines that seem to only work on the third Thursday following the fifth month after the Lunar eclipse. But it's likely a combination of disinterested staff and machines that require more involved maintenance. Not to mention, there's several points of failure. Not only can various parts of the machine break; the drum that spins the mix, the compressor to keep the mix cold, leaks in various hoses and lines, but you can simply run out of mix.
