My intuition tells me this is the problem. I moved away from purchasing any type of grab and go food about ten years ago and I think a lot of consumers have joined me.

it might never make it, depends on where you live. where I live, they were banned because must accept cash, and they can't sell things like booze because id checks, so you end up having a bunch of humans around anyway, which kind of defeats the purpose of installing hundreds of cameras and other expensive systems.

Automated cash registers exist and are widely used, and are much simpler technologically than a scanner-less checkout. Amazon is choosing not to use them.
