A Simple Plan

Car A needed to go in for service. Driver 1 took Car B to work this morning. Driver 2 took Car A to the shop and picked up a loaner, Car C. Driver 1 drove Car B home after work. Cars B and C are in the garage, Car A is still in the shop. Tomorrow, Driver 1 will take Car C to work. During lunch break, Driver 1 will pickup Car A and return Car C.
