FWIW, I've been using Amazon Go stores regularly for a while and have never had any issues.

There's a link to dispute the receipt should something happen, right on the receipt itself. Now this is specifically Amazon Go app, but I would expect it to be same for other retailers.

Edit: I see that this is a little bit different than Go stores. It's far less convenient, but you can still get the receipt in your email by visiting a kiosk it seems.
