Blorf, what an awful post office. They go out of their way to charge you extra fees, they open your packages and charge you extra shipping costs if the person who sent you the package didn't pay correctly or pay enough based on their criteria. This happening once or twice is understandable but it happens all the time. I will no longer be getting anything shipped to me at my residence, have to use a friend's address just to avoid this post office. To top it all off, the staff at the office is generally unpleasant, not everyone but for the most part. Cheer up folks, you've got a great job serving a quiet little suburb of Long Island! Why are you so miserable?? Put a smile on and be helpful, good grief.
