As someone who has worked behind a checkout till it is not a job I think anyone is dying to do.

For you, as the customer, maybe it seems cute and fine as a job but from my time in the job it's basically hours of mindless labour that teaches you little and offers no room for growth.

Your opinion on this is actually kind of despicable. You want people to perform robotic menial jobs because you feel like it adds humanity to your shopping experience but you seem content to ignore the fact that the job in question is a boring, tedious slog.
