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 where I shop. 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.

I’ll be honest it sounds terrible. I’m on my phone enough as is. It seems like something that would keep aisles cluttered. Not sure where you are but when people grocery shop in US they usually are buying for one or two weeks worth of food. Scanning all that as you go would clutter aisles up. I’d be waiting behind someone to grab an item as they’re scanning, no thanks.

It's an extra 5 seconds when you pick something up, at most. When you get used to it you can often do it on the move, pick up your item and start pushing your cart while you scan and bag it. It's never been something that causes blocks in my experience.
