Glory Ltd is a homeware store. Martin, one of the store's employees, whose responsibility was to collect up shopping trolleys from the store's car park. As Martin was pushing a long row of trolleys, he lost control of them. The trolleys crashed into a car owned by a customer. Charis, who was a customer and was about to collect her car, witnessed what happened. She went to the store manager and reported what she had seen, making it clear that the accident was Martin's fault. Martin overheard this conversation and became very angry. Half an hour later Martin was off work. He waited outside the store, and when he saw Charis left the store he followed her to the car park and pushed her violently causing her to fall to the floor, breaking Charis' right arm. Charis had suffered arm injuries from playing badminton in the past two weeks. The new injury caused by Martin's violence made her injuries worse than they would have been otherwise and she had to stayed for an extra month off work at home. While staying at home, Charis felt so boring and one day she decided to paint her house. While carrying a heavy bucket with her left arm, she was not able to hold it and her left arm was injured.
