The scanning isn't the problem. It's the pedestal the size of a postage stamp upon which I'm expected to balance $250 worth of groceries. And if I fail to do so, the machine freaks out. And even if I do succeed in stacking all my groceries up as demanded, the machine still freaks out. Want a beer? Fuck you, wait god-knows-how-long for an attendant to come appease the machine.

I always go to a human cashier whenever the option presents itself, simply so I don't have to deal with the miscarriage of engineering that is the self-checkout machine. Unfortunately, my local grocery stores don't staff their registers very often anymore.
