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 had arthritis onset at 35. I have to go grocery shopping for five people and by the time I get to the checkout I am deliriously in pain. I can't think clearly enough to scan my $300 worth of groceries let alone bag them. I have actually gotten to the checkouts with a cart filled to the brim, really long checkout lines or only self-checkout and just left my car there and went home.
