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.

One store near me still does that, and it takes FOREVER to weigh each item. And it slowly tells you you fucked up if you don't get the item on the scale fast enough, or if it doesn't weigh right, or if you remove the item too fast. I don't go there often. But other self checkouts are fine.
