NBA basketball is a service. We are the customers and the teams and their players are the providers. If you're not satisfied with the service that has been provided to you, you have the right to make a complaint. We're definately not satisfied with the basketball that we're paying for and booing the players or leaving the arena before the final buzzer are some of the ways we can show that the product that we've got doesn't meet our demands. We're paying a big part of Amare's and Carmelo's max contracts and we except certain quality of basketball in exchange.
