But the day ZeroCater misunderstands a dietary restriction, or just shows up with something I can't stand, there would be a big problem.
I intentionally order only things I know I'll like and can eat so I don't go through the day hungry and pissed off. The model of "tell us when you don't like something" might eventually approach something semi-reliable, but in the mean time there's going to be a lot of wasted food and low blood sugar.
That's true, but nothing's perfect. Once so far I have misread a (somewhat-confusing) menu item and ordered meat by mistake.
But that's probably a little rarer than a failure of ZeroCater's model to satisfy every person, and I came away from my Waiter.com error primarily blaming myself, whereas since ZeroCater claims they can satisfy everyone without having you explicitly choose, it's really their fault when they fail at that
