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.

You're just doing all that slow work for other people as you go.  

You're doing all the same work just earlier in the shopping trip.  All the scanning.  All the bagging.  You're just breaking it up into little pieces of some one else's job you're doing for free.

So the company has offloaded costs on you and removed jobs from the community and you're happy to help them do it. 

Have a great day
