Reading Passage: Abel decided to spend a quiet staycation at Hotel Fawlty. He approached the hotel reception and enquired with the receptionist on their special weekend rates for a night's stay in a single deluxe room, and the receptionist responded with a quote of $150net.A prominent sign stood on the reception desk with these words: "CASH ONLY:unless we receive your cash in full, there is no deal!" Abel did not sign any form. He paid for the room as directed and was then given a breakfast voucher. The voucher was about the size of a credit card, with clause 1.1 printed in pale ink and 6-point font on the reverse side of the voucher. There were also signages in the hotel lobby and reception area displaying the same clause. When Abel entered his room, the first thing he saw was a huge TV screen with these words staring at him: "clause 1.1: Hotel Fawlty accepts no liability for any injury or other damage howsoever caused." The hotel also made announcements through its public address system for visitors and hotel guests to be aware of its disclaimer posted on the signage.

The next morning Abel decided to take a dip in the hotel pool but cut his foot on a broken tile as he entered the pool. He hastily returned to his room to apply first aid but found his expensive watch stolen. The hotel cleaner had negligently left his room door unlocked and allowed a thief to enter and take the watch.Assume that the hotel was in breach of contract and was negligent in failing to keep the pool safe and his room secure.

Question: Advise Abel whether the exemption clause is part of the contract.
