Is amazon going to tell me that up front? In the restaurant case the manager can explain the issue to the customer and ask them not to come in again. It becomes immediately resolvable whereas in your example I have no idea what just happened to me.

I live in a town of 2 million people. These vibes have zero impact. Add them to a database that can be tied to my credit card number? Now they have real impact. I don't think that's a reasonable or desirable outcome.
The problem with these systems isn't their mere existence it's their draconian implementations.
