After we finished work on the deck we drove around different places selling watermelons out of the back of Norm 's truck . We got about 150 for $ 100 and sold them 1 for $ 3 or 2 for $ 5 . We figured it 'd be an evening of easy money . Only we only sold about 20 so we did n't even make back our investment .
According to the above context, answer the following question.
Why is the person selling watermelons ?


They are looking to use it as a side hustle .
