Dave is a serviceman for A1 Heating and Cooling. One day, after repairing the a/c at Harry's house and en route to the next repair, he stopped at a fast food restaurant to get a sandwich at the drive-through window. As he was leaving the parking lot, he accidentally hit the rear of Zena's pick up truck.
