Enforcement systems like this stress me out because I hate being policed. It’s much better to have the routine of a cashier or a turnstile than to be randomly inspected and assumed guilty until proven innocent.
I agree. I would actively avoid shopping at any place that did this. But I already know that "cashierless" stores aren't my cup of tea in the first place. Since I'm not the target market for this kind of stuff, my opinion is meaningless.
