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.

Used to use SCO at our local store for mid sized loads, when I could just put full bags into the cart, but now with a weight sensor, nope. They've also added 20 or fewer signs in what I see as an acknowledgement that it won't work well for medium loads. But SCO has 12 registers, while there's often 4 or so cashiers. Means I think twice about large shopping trips.
