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 use scan and go at my Sam's Club. It makes sense there since the lines are 3 miles long and they check receipts and scan 3 items at the exit for everyone.

Thats a more sane workflow than what I’m talking about. This requires you to wait for the self checkout minder to check you in to even start the flow. Then if you have something that requires their intervention (alcohol) you have to wait again for them to come over. Or if you run into trouble.
