Loss of jobs...might be a prickly problem...but lower number of necessary employees allows the able to rise with incentive to stay. Retail sales has a very high turn over rate with a double hit, severance package, search expense, training costs.
Net effect would be very positive across several levels.
Not sure about that, esp. w/ the automation these days that are available: Unload into rack ABC/slot XYZ, customer comes, robotic forklift/etc. retrieves from ABC/XYZ for delivery.
Anymore (see: fast food), there’s little incentive for customer service, hustle, friendliness, etc. That robot can do a better job all around.
