The question remains - what's the barrier to entry to becoming "certified" as an ice cream machine cleaner?
Is it legitimately a difficult cleaning process that requires an extremely specialized skill-set that only the High Priests of Ice Cream Machinery are able to perform?
Or, as seems likely to me, cleaning the machine is relatively simple, but the ability to reset the "time since last cleaning" setting may be artificially restricted?
If I were the manufacturer of these Taylor ice cream machines, setting them up with a "one of our certified technicians needs to touch them at least once every 14 days, or they stop working" seems like an excellent way to seek rent / generate passive income.
