Scofield decided to book a room at the Suredie Hotel for the night. The hotel manager told him that since he stayed overnight and left early the next morning, he should pay for the room in advance. Scofield agreed and paid for the room in advance. Then he was taken to a room on the fourth floor. As Schofield closed the door, he noticed a sign behind the door that read: "Management accepts no liability for any damage or loss of items stolen from these premises. All guests are advised to deposit valuables the hotel manager will keep them in the hotel safe until requested." Schofield was wearing a $100,000 Gold Patek Philippe watch and a 2-carat diamond wedding ring. He put them both on the side table beside his bed. Feeling hungry, Scofield decided to go to the hotel cafe for a quick meal. Forgetting to put on his watch and ring, he left the room and locked the door behind him. While waiting for the elevator, Scofield realized he had forgotten his watch and ring. However, he decided that he would only be away for a short time and there was nothing to worry about. When he returned from dinner, Scofield realized that his watch and ring were missing. He called the manager to inform him of the loss, and after a thorough search, neither item was found. A) Briefly explain how to make the escape clause valid in the contract using the relevant case method. B) In the circumstances, please advise Scofield whether he is able to bring a successful legal claim against Suredie Hotels for his loss. Explain your answer.
