My guess on that would be that the old cup machines would not have been placed in low traffic areas and therefore would have had to be serviced every couple of days. That would have likely included cleaning and refilling.

Like at a break room at a large company or something like that? That makes sense. Thanks for letting me know about these machines. I think I will wait on a syrup dispenser for now because I might be able to get a gas pump which right now sounds like a lot of fun to play around with.
