Siggi's responded, saying it would foot the uncharged yogurt bill, although an Amazon executive later admitted it was a snafu on the mega-retailer's part.
"First and foremost, enjoy the yogurt on us," VP of Amazon Go Gianna Puerini told CNBC. "It happens so rarely that we didn't even bother building in a feature for customers to tell us it happened. So thanks for being honest and telling us. I've been doing this a year and I have yet to get an error."
Peurini also said the company has no intention to introduce the cashier-less technology at Whole Foods at the moment. Being that Amazon Go has only been open to the public since Monday, that's probably a good thing, given the multitudes of free yogurt that might be flying off the shelves as a result.
