Except that's the point. It is the same store. It is two different cashiers. The second one doesn't know you got the ID from the first one, that's why it works. The point is that if a store like that existed, it would be stupid as fuck.

Also, at least in ChatGPT, it has access to every other session, so you're never working with zero context unless you create a new account (and even then they could have other fingerprinting, I just haven't tested it).
