Larger grocers here have self-service checkouts here (Calgary) and they receive regular use. Many shoppers prefer them, since they can see if the items are properly entered.

Face it- many jobs have gone in industry as well as in retailing, replaced by automation and multitasking. Finding employment will be problematical until some means of providing for surplus workers is found.

Companies that stick with large numbers of unnecessary employees will sink, so shopping at them is no solution.

A revolution of a sort is in progress. I forsee factories with an engineer or two at the top supervising robot processes.

Finding means of supporting no longer needed humans will be some time in coming.
