Alia placed the following advertisement in the notice board of Seven to Seven Stores: "Missing a dark and grey colour Persian Cat. The cat is wearing a silver necklace with a heart shape pendant with a written name 'Kitty'. Anyone who finds the cat may return the cat immediately. Do contact Miss Alia at telephone no. 015 343900, and rewards will be given for those who returns the cat". Last week, Tam while jogging at a park near his housing area, found a Persian cat. But he decided to keep the cat at his home. Yesterday morning, Tam went to Seven to Seven Stores to buy a newspaper. Then he came across the advertisement by Alia and it had reminded him that the details of the cat specified by Alia are the same as the cat that he found last week. Immediately Tam contacted Alia toinform her that her cat was safe with him. Then Tam returned the cat to Alia, but when Tam enquireas to the rewards as promised, Alia argued that her advertisement was only as an invitation to treattherefore she has no obligation to pay the rewards to Tam. Tam came to you to seek for your legaladvice.
