The automated walk out service wasn’t a con. It was a shortsighted, honestly s***** idea, that was never able to be brought past the human oversight stage.
Con requires intent. I’m absolutely certain they fully intended to make it a completely humanless system. They failed and drug their feet trying and now they’ve shut it down.
If it’s a con, what’s their long game? What are they gain from having humans watch the store remotely? Is it tech just so neat that they’ll have a lot more shoppers than a regular store? Do they save so much in on-site staff that it’s cheaper to run than a conventional store? There’s no advantage here that would make it a worthwhile con. It’s a failed moonshot that they ended up manning with people to see if they could make it work that’s all.
