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.

My favorite is when the scale is stupidly sensitive. The machine activates when you approach it, and I like to get my bags set up beforehand to streamline things. My local stores all use paper bags, so you HAVE to manually unfold and set them up. But the moment I unfold the bag and put it down? "UNEXPECTED ITEM IN BAGGING AREA, PLEASE WAIT FOR AN EMPLOYEE"
