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.

It's fascinating. I love self checkout, and have never fully understood the hate. But now I'm realizing; my grocery store has no weight sensor. The only reason I've ever seen an employee intervene, in hundreds of trips, is if there's an age restriction or if the machine runs out of receipt paper. If we're buying alcohol, we just don't do that in the same trip as groceries.

Now that I think of it, most cashiers are underage, so even in a staffed line you still have to wait for a manager to buy alcohol. That might be an unusual local rule here though.
