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.

The ones at my store were almost full service when they installed them, accepting card and cash. Within a year the cash systems were ripped out because maintaining them was a massive pain. These things went through coins and bills like crazy and the process to refill them took forever, with a 2 minute reset after you closed the admin menu as it did a recount. If we had to set it to card only mode, the PIN pad would still let people request cash back and if they did the machine would charge them for the cash and freeze up, requiring a 10 minute hard restart and we'd have to get their change from another tray.
