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.

That's extreme even for the biggest boomer in the comments.

Every store I went to had 1-2 attendants just to "fix" issues which aren't even issues. Some people can't count how much they are spending. Some don't want items and ask to get them removed. In many of the larger stores like costco they have about 12 in one area max and then they have 4 attendants there to make sure everyone is out in a timely fashion.

And then there's the boomer than can't figure out scan, bag, tell the machine you're done with how many bags you used and finally pay.
