The jokes about 75 checkout lanes and 2 cashiers still apply...cos they’re true.
But speaking of cameras and cistomer service, I once saw 2 college students videotaping each other in front of a Walmart. Totally innocent, just using the building as a backdrop.
Well, the manager and assistant manager were outside like a shot, asking the girls why they were taping and to stop it. Perfectly understandable ans predictable given company policy and their shaky PR track record, but I thought it was amusing to see what would earn extra special attention that quickly.
Considering that you can get a 128 GB card smaller than your fingernail and a camera/microphone combo not much bigger, I expect people to start wearing cameras constantly just in case something interesting happens. Companies and cops will be unable to stop being videoed constantly just as we are unable to stop them. People won’t even have to reach for a phone, just look and record.
