My thought when opening the post was basically, "Can you imagine the depths that American corporations would sink to in a market where they can totally conceal the flavor, size, quality, etc. of their products until after the sale, and not have anyone from the company present, making them totally immune to any negative feedback?"
Presumably the companies behind these things in Japan are at least delivering a somewhat acceptable food item. I wouldn't be surprised in any way to find an American version of this thing dispensing literal dead rats.
My experience here. Had one a place I worked which did breakfast foods (yogurt, breakfast sandwiches, breakfast burritos , etc) with a small microwave slot to heat up after it vended. Food was absolutely gross and it was always dicey if anything it vended was still in date. Only nice thing was the front was see through so you could check which items had visible mold and avoid those...
Was cheaper than the cafe and had better hours (all of them) for my shift, but I don't think the trade off of rolling the dice on food poisoning was worth it lol.
