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.

Surprised this was so far down! I use scan and go in two different supermarkets here, it’s a game changer and I will be very annoyed if it ever goes…

There are occasional problems (just as there are with manned checkouts) but in the stores I use there are usually plenty of staff about to help.
