The superstore in my city has self-checkout machines. I <3 them enough to eschew the walmart built across the parking lot for them.
But really, what I've noticed to be the actual problem is that they never have enough people working cash. It's as simple as opening more than one or two of your 12 lines during busy time.

they have to be shown as a benefit to manufacturers and everyone agree on a standard. tough to do. Walmart had big plans to require suppliers to do so already years ago but must have softened up on the plan.
