When you use goods and services they can either be for yourself or entertainment. Lets take brushing teeth for example. You might have to go to the dentist so they clean your teeth every month. So you but toothpaste at a store and are using it as a good to brush your teeth. Having soda because of the taste is just simply because we love the taste and think it is a go. But be careful buying to many goods could leave you in trouble with the money you have. Have a great day :D
