I'm a huge self checkout fan, but I think we need more perspective on how shitty ours is sometimes. Loblaws and all of them are way behind on how it should work. Look at the Netherlands and how it's often done there, you walk around with a scanner so you can scan as you go and quickly pay at the end.

Or even better, look at how Uniqlo is doing it. It's all RFID, so you just drop your basket on the checkout, and it scans it all for you basically instantly.

The problem isn't self checkout, it's that the grocery stores are using it to purely cut costs and don't actually care if it's better for the consumer in any way. But hey, at least it's easy to "accidentally" not scan something right now.
