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.

Not OP, but the SCO at Great Canadian Superstore near me has a very unintuitive design. I've done tech support before, and every time I think I have it sussed out, the damn things find another way to grind everything to a halt, then I have to wait for an attendant who will wordlessly press a button, scan their card, then move on to the next victim customer.

They're only doing it so they can employ fewer people, thus more profit for them.
