There's also the "bundling". I once stole 3 beers accidentally. 4 bottles of beer were bound together with a cardboard piece at the top.<p>As it turns out, there's a barcode on the carboard. BUT there's also barcodes on the bottles.<p>So what happened? I swooshed the 4 bottles of beer in front of the self-checkout scanner. It beeped. Of course, it beeped because it scanned a barcode on one of the bottles, not the one on the cardboard bundler thing. 1 beer bottle was charged, not a set of 4 of them.<p>I did not realize until I got home. And I've had bad experiences with this, so sorry, I'm not going back.<p>So yeah, I think there's definitely a decent percentage of "fuck this self-scanning shit", especially when an item presents you with difficulties or subtleties when it needs to be scanned at the self-checkout.
