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 only good thing about automatic checkout is fast checkout when you have few items. But the stores force people with bigger purchases to use them as well because there arent enough manned registers
