Question: Tina contracts glandular fever, and during the four months she is off work, she tells Brad that he can order petrol while she is sick. During this period, Brad negotiates supplies with Caltex. Brad orders fuel from Caltex every fortnight. Tina returns from her illness, and tells Brad that he should no longer order petrol and that matters will be conducted as they were before she was ill. However Brad, who enjoys the increased status of dealing with the oil companies, ignores Tina's instruction, phones Caltex and orders 30 000 litres of fuel. When the truck arrives to deliver the fuel, Tina is furious (as she has already entered into a more advantageous arrangement with BP). She phones Caltex, and denies that there is a contract between her and Caltex, stating that Brad was acting contrary to instructions when he placed the order.
