All retail environment's in the last 10 years have been moving towards automation. Self check out and so on. Why? Because a self check out terminal for example does not; complain, call in, steal, play on a phone all day, quit, not show up at all, it's a one time cost up front, no medical, no drama, does not develop a negative attitude at the drop of a hat, no turn over rate and the list never ends.
Do you know what self-checkout terminals don't do? They don't help confused elderly customers, stop people who steal, make things faster if a person is learning how to use it for the tenth time, make things faster when they malfunction (which they do a lot!), provide customers with human connection many are still looking for, ask customers to do the work that should be done by the store, and the list never ends. I know people who don't use self-checkout because they don't want to help corporations replace employees. The number of those people is growing, not shrinking. We're not that easy to replace.
