I believe so. Just to hit on your point of human interaction, when I go out in public, I make it a point to say hi to people. Of course not everyone, but people you run into at the door going in somewhere or seated at a table near you in a restaurant. I think this was lost on Covid and people don’t realize they missed this interaction.
Back to the topic, it seems when I do use the self checkout, I always have a problem scanning a bar code due to plastic interference, wrinkles, or just plain faded. There will always be a job for a helper when it comes to me. Lol
