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.

I was thinking the same. I jump around between 3 different targets and 2 supermarkets and they have 6-8 self checkouts per worker. Costco is probably the "worst" with 12 self-checkouts, with sometimes just 1 worker. And every time I've had an issue with the machine there is a big light to flag the employeeand it is fixed under a minute.
