In the real world, tomatoes come graded. You pay a lot more if you want them all exactly the same size. They need to be washed, and frequently have woody stems that need to be excised. I didn't see that happening automatically.
And onions don't come pre-peeled in restaurant quantities. The pickle tube is going to jam. The condiments might signal you when they're out, but the nozzles are going to need a good cleaning.
I wonder if they're planning on going Juicero and selling their franchisees preloaded tubes.
