Some people won’t go to Walmart anymore because of this self check out thing. They now only have one line with a cashier and it takes you half an hour to get through it. Some people refuse to check themselves out and will no longer shop at stores that have converted.
I find that these self checkouts are a great time saver. For me it is a game to see how fast I can run my purchases through and be out the door. I am fast. Others struggle. Some day everything will have RF chips. You just load up the basket, run it through the reader and everything is instantly checked out at the same time.
