Greg purchases a bus ticket from Brisbane to Rockhampton for $60. He ignores a clause of his contract with the bus company (cl 16.5) that prohibits passengers from taking food or drinks onto the bus, and sneaks a cup of coffee aboard when he takes his seat. He spills the cup of coffee, leaving a small stain on the seat. The bus company is now relying on a further clause of the contract that allows them to charge a passenger $500 for any loss or damage that occurs as a result of any breach of cl 16.5. Greg wishes to know if he must pay the $500 demanded by the bus company. Advise him. (Ignore any relevant statutory provisions. Your answer should be half a page or less).
