Nаdine hаs been intо а McDоnald's fast-fоod restaurant many times with her dad to get ice-cream. Usually, she tells the worker what she wants herself. However, on the way home from school one day, her dad went through the drive through with Nadine for the first time. Her dad tells her to say what she wants to the microphone, but she's totally confused about how this is McDonald's. Why?
