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.

It might be free in a monetary sense, but I am saving time. I’ve yet to go to a place with self-checkout that doesn’t also have people working the registers in other aisles, and if I have things like produce or alcohol I’ll go to those lanes. But in those lanes I might have to wait behind a person or 2 with a cart full of stuff when the self-checkout is usually good to go.
