I'm pretty sure this kind of use of surveillance cameras/data wouldn't be legal in the EU, so that's why you might see lots of people who are more enraged by this than they supposedly should be... You're allowed to put up surveillance cameras and record things, but if you actually want to check the recordings, then there's requirements. The exact requirements probably differ between countries, but I imagine you need at least a well-founded belief that you've been robbed in all of them. And even just for that use-case, you need to put up signs that make it evident that customers are being surveilled. For something like this Amazon Go store, you'd probably need people to sign a disclaimer to ensure that they've understood what they're getting themselves into. And you might have to allow an opt-out clause, so that people can choose to not be surveilled and then check out normally. That last part isn't yet in EU law, I don't think, but with the upcoming General Data Protection Regulation (25th May) it is, or at least it's going to be hard to argue that you don't have to allow opt-out. The relevant part of the regulation is section 4 in this: https://gdpr-info.eu/art-7-gdpr/ https://gdpr-info.eu/art-7-gdpr/
