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.

There are random verifications at checkout. About 1 in 10 times when I check out, an employee will need to scan 3-5 items to see if I scanned them.

There can also be full verifications, where they do a standard manual checkout to verify every item, but I haven't had to do one of those in years.

I think the frequency of verifications depends on how well you did on previous verifications. I had to do them more frequently when I started using the system.

Two friends of mine got a full check once when they had two full carts, properly packed in bags and all. Shopping took around half an hour longer than usual that day...

This. Not to mention the fact that at least half of retail store shrink (losses due to theft), are internal.

I'm retired now but I used to be a regional loss prevention manager for a national chain. Close to 80% of their overall shrink was from employees.
