They have not solved the automated check out at grocery stores or Home Depot yet. I have NEVER gone through one where I didn't need a clerk anyway. It's like when ATM's first came out, they were not user friendly and always broke down. However now they are great. Never go to a teller anymore. Between ATM and online banking, they can close the branches. But grocery stores and HD need to work on those infernal machines some more. However I do believe they will get them right someday.
