Gilles, who is 16 years old but looks much older, bought a snowboard from Eva’s Sporting Goods. He paid the $750 price with a promissory note that was payable in three monthly instalments of $250 each. Eva stamped the words “consumer purchase” on the note at the time of the sale. Unfortunately, the board was stolen the first time that Gilles took it to the mountains. He believes that he should no longer be required to pay for something that he no longer enjoys. Not surprisingly, Eva has a different opinion. She believes that Gilles got what he wanted and that he is liable to pay the full price. Is Gilles liable on the note? Explain your answer.
