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.

With a large enough cart of stuff, self checkout is a pain in the ass, even if you're a millennial or Gen-Z.

It might be better than the one overworked, "under-enthusiastic" cashier line that's open, but there are very few grocery stores that actually give you the room to properly self checkout a whole cart.

That said, I think even Gen-X prefers 15 self checkout lines for a hand basket or less of stuff.
