Poor pick up and delivery to our block on S. Mary Ave. Lately, our delivery service has been poor, at best. Today I received the mail for my next two neighbors. Delivery person didn't even stop at their houses to pick up outgoing mail like he couldn't be bothered. We sent out 2 letters over a week ago that haven't reached their destinations. We do not want this delivery person on our route any longer as this is an ongoing issue. The Hunt's @ 1473 South Mary Avenue, Sunnyvale CA. 94087
