Child sized Volkswagen Type 2:
At first, I thought they were interesting. Then I realized that everyone had to get ice out of it, no more other ice cube machine. This includes those of us, like myself, that like iced tea (plain, unsweet, like God intended). This — plus only one soda spout — means that whenever it is even mildly busy, there is a holdup at the machine. That holdup is longer if there is anybody who has never used this sort of machine (oh wow wouldja lookit that) or doesn’t already know exactly what he/she wants.
And above, the other reason I dislike these machines. Gross.
