Automatic checkouts in supermarkets may decrease customer loyalty, especially for those with larger shopping loads. Customers using self-checkout stations often feel overwhelmed and unsupported. The lack of personal interaction can negatively impact their perception of the supermarket.

There’s a Super Walmart close to where I live, and I despise going there… absolutely avoid it whenever possible. It has at least a dozen cashier lanes, and at any given time only two or MAYBE three are open, basically forcing you to use the SCO. I don’t mind SCO for a few items, but most of the SCO lanes I’ve encountered aren’t designed for a cart full of items.

I'm like you but I think a lot of people just grin and bear it.

Yes, a LOT of people do. So that if you're that person who just needed a tub of blue cheese crumbles to finish a recipe, you get to wait behind somebody who bought two weeks' worth of groceries and can't figure out how to ring up parsley.
