Annie made a reservation at "Frederico's" to meet some friends who she hadn't see for a while. While Annie was getting a round of drinks from the bar a waiter carelessly spills a tray of drinks onto Annie's expensive designer labelled handbag. She had left the handbag on her seat. Inside the handbag was an expensive Apple watch, iPhone and iPad, these had been affected by the liquid. When she complains to the restaurant manager, he directs Annie's attention to a sign on the wall that states:

'The restaurant takes no responsibility for goods lost, damaged or stolen'.

Annie didn't notice the sign when she walked in because it was obscured by a large cactus.

What is the legal issue at hand? What are the relevant legal rules that apply to the situation? Can Annie seek compensation? Is an action likely to succeed?
