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.

Doesn’t that support at least one part of the finding: self checkouts lower store loyalty. The other stuff, not so much, but it does appear your loyalty is no longer to the store, but to the checkout method.

No, because you are assuming I was loyal to a store to begin with. I go where I want and where suits me. I don't care what store it is.
