Amazon Isn't Killing Your Business, You Are

A few days ago, I went to the store to pick up a few items after work, which was the peak time in retail. When I went to pay, I looked at two registers with cashiers and very long lines. I then chose to contend with self-service, and when I got stuck in the particular sequence I was supposed to do to pay, the human who in the earlier days of self-service stood around helping people become familiar with the payment machine was nowhere to be found.
