Years ago, husband and I had a 7PM appointment 1 or two times a week about 50 miles away. We'd both rush home from work, then head to town together. Often we stopped at McDonald's because there was one convenient to our way home. We never drove through. Nearly every time the young person behind the counter had trouble with change.  The next morning in class (2nd grade), we had a change counting lesson. Although we counted change at other times, my students would ask me if we had gone to McDonald's again. LOL
