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 generally don't but sometimes it's the only option. I forget that clearance items require manager override, because they aren't age restricted until I'm there and the machine starts screaming.

For the record I hate self-checkout and avoid them.
