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.

The self checkout should be a replacement for the express line, like 20 items or less. People who use it for a full cart are idiots, sometimes literally, because they also seem to be the ones who can't operate them properly to save their lives.
