I remember a few years back when I went into my banking branch to deposit a check my insurance company had sent me. When it was my turn at the teller, and I presented my check to her for deposit, and she said, rather rudely: "You can do this with your phone, you know?" On my way out of the bank, I remember thinking to myself that she was, essentially, putting herself out of a job by encouraging people to use their phones and not her. Turns out I was correct.
