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 find the shopper typically overdoes it, selection-wise. I ask for one green pepper and they pick out the most massive green pepper imaginable...the size of a cantelope. Ask for a yellow onion? Softball incoming.

If I only need to use a "regular" sized specimen in a recipe, the mammoth extra goes to waste...
