We know some people have differing opinions on [wearing face masks]. We also recognize the role we can play to help protect the health and well-being of the communities we serve by following the evolving guidance of health officials like the CDC. We appreciate the understanding and cooperation of our customers and members in wearing face coverings to protect their safety and the safety of our associates.
