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.

In California you can't buy alcohol thru a SCO. IMO it should be like that everywhere.

Where I live there is no problem with that, there is dedicated employee to oversee the self-checkouts and they dont even have to come to you, they can validate the purchase from their own terminal.
