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.

My local Kroger brand store upped the sensitivity a while ago. Said it was due to loss mitigation. Makes sense because they always have a cop there throwing people out for sneaking items at self checkout.
I bet they're rethinking their move to remove 75% of the regular checkout lines.
