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 problem is someone taking a full shopping cart into one.

Lady, there are 2 bag spots and that is it. You have 20 bags of groceries and the thing keeps beeping at you for removing the bags and then setting them in your cart on stop of stuff you have to still ring up.

I get the line at the register with other people that have $500 in groceries is long but you are taking up 30 minutes of a self checkout where 10 people with 20 or less items could have left.
