The photos below are from an ice machine mounted atop a fountain drink dispenser at a very large national chain of gas station/convenience stores in Orlando.

The photo below is where the filtered (supposedly) water cascades over the evapoartor and freezes onto a metal plate that forms the cubes.
Here is a close up shot of the sections that make the cubes.
For comparison, here is an ice machine from a national chain of restaurants and bars. This demonstrates the difference in decision making at a corporate level to end maintenance programs due to finances.
