Mary asked Sarah for a ride to work. Sarah was happy to take her on the condition that they listen to their favorite childhood song on the way. When they returned home, Mary said she would take Sarah to lunch the following day. She wanted to thank her for the ride and the trip down memory lane. The next day, Sarah showed up at noon with her appetite. Unfortunately, Mary refused to take her to lunch. What will likely happen?
