I’ve lived in Miller Place for over 40 years and until recently have dealt with unfriendly, incompetent clerks. I now want to commend Giovanni and Chris at the Miller Place P. O. For their cheerful, pleasant, very competent dealings with me and my postal issues. Keep hiring the best! Sincerely Mrs. Ann Schwartz. (Box holder)
