Ash has purchased a first class ticket for her flight to Sydney, entitling her to use of the Kwantus Club lounge at the airport while waiting for a flight. While Ash is getting a drink from the bar, a waiter carelessly spills a tray of drinks onto Ash's expensive laptop, which she left on her seat. When she complains to the club manager, he directs Ash's attention to a sign on the wall that states 'The airline takes no responsibility whatsoever for goods lost, damaged or stolen while using these facilities'. Does the sign prevent Ash from suing the airline for compensation?
