And you’re right, this is by far the best checkout experience. It’s what Amazon wishes they’d built.&lt;p&gt;I can’t imagine there’s that much untapped profit in the grocery business that Amazon could turn a profit with such an expensive and unreliable mess like Just Walk Out and I find it’s so typical Amazon to find out that the man behind the curtain is actually a bunch of offshore workers in India.</text></comment>
