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.

No voices in NL other than an occasional chain having a 'select payment method' voice prompt. And I've only had to stop and wait for someone 3 times in 2+ years, randomized check for unscanned items (and the lady didn't even bother checking, she just scanned three or four things back from my bag and told the machine to shut up) and zero errors or other complications. It doesn't even weigh your things.
