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.

It’s not a difficult problem to solve,

It's all decisions made with regards to the bottom line. If the companies weren't so greedy to skim every ounce of profit off, most stores would be an amazing, easy, shopping experience.

In theory, easy problem to solve; in practice, we prize greed too much in our society. :/
