Tuesday’s reply from Smith’s Food and Drug defending its Scan, Bag, Go program left me with many questions.

You are getting customers to do work of your cashiers. Does that mean your customers who will save you money get a discount? Of course there will be fewer cashiers, who will be assigned to lesser jobs (like stocking shelves)? Will your former cashiers be paid less money? Will hackers love to get more information that is floating around, and shoplifters will not be watched as much? Will more guards or new “guard machines” be needed? Will cash still be accepted? Must you have to have a cell phone to shop? Will payments be automatically deducted from your bank account or service refused if there is not enough money there? Will the next step be robot shelve stockers? Will the robots still smile and help? Will there be still enough live humans to help customers?
