Amazon’s cashierless store of the future opened yesterday to great fanfare. It required over a year of R&D while the company’s tech savants perfected the cutting-edge automation used by Amazon Go’s no-line shopping method (things like computer vision, sensor fusion, and so-called “deep learning”). Basically, an inordinate number of cameras capture the store’s every angle, allowing customers to enter empty-handed, then exit with bags full of sandwiches, wine, soda, individual-serving-size granola bars, and a thousand other things — all of which the cameras, in theory, detect.

It appears there are still some kinks to work out. While a New York Times reporter who got an early look tried to test the robots’ mettle, he was promptly discovered, and his Amazon account was charged for the item, a four-pack of soda. But CNBC tech reporter Deirdre Bosa might not be Amazon’s favorite person right now. It appears she’ll go down as Amazon Go’s first-ever shoplifter, a feat she achieved just hours into the store’s grand opening:

Feels like I just stole all this stuff. Also way easier to buy more when you know you’re not gonna see a register. Still waiting for my receipt to be convinced I didn’t steal something #AmazonGo pic.twitter.com/x4lbLGoDv2 — Deirdre Bosa (@dee_bosa) January 22, 2018

Her double-question-mark confusion is actually an interesting consequence of Amazon Go. Because it turns shopping into an existential riddle: The store encourages people to “Just Walk Out,” so what even is the line between honest shopping and would-be shoplifting?

Even Siggi’s isn’t sure:

oh no! It's ok, that one's on us 😉 — siggi's (@siggisdairy) January 22, 2018

Thanks Siggi’s! But I think it’s on Amazon :) https://t.co/HrjFrZmgpt — Deirdre Bosa (@dee_bosa) January 22, 2018

Bosa says she just put the items in her shopping bag and walked out as instructed. She ’fessed up to Amazon immediately afterwards, and Amazon Go’s vice president Gianna Puerini told her to “enjoy the yogurt on us” because that goof “happens so rarely that we didn’t even bother building in a feature for customers to tell us it happened.” The exec adds she’s been using the platform for a year and has “yet to get an error.”

So it sounds like the company isn’t too worried. And maybe that’s good — it can focus on solving the other snags popping up that also seem counter to Amazon Go’s ethos. For instance, interest in the store is apparently already creating lines:
