Back in the day on rural routes you could ask them to bring you other items... like milk, sugar etc. I once had a woman ask me to pick her up a loaf of bread. (This was in 1992) I told her we don't do that anymore. She got mad and said, "Well, you use to bring me what I needed!" So yeah, I can see someone saying, "John can you stop by Annie's house and pick up Billy for me on your way out here."
