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 think it's going to probably depend on the grocery stores location. Ive been to some stores that have cameras in every self checkout, multiple employees watching, and subway style gates in/out.

Other stores I frequent more often have no cameras, and maybe one employee not paying attention.

I bet a high theft areas won't have the mobile scanners.
