    Had to stop by to get something mailed out. I was a little short with the lady as was in a hurry, she did a great job though. They take care of things well here

    Like everything in this area of area, Connecticut, rude and arrogant they close for lunch. This is not Europe or South America. I’ve worked at the Postal Service in Armonk and Somers, New York and nobody closes for lunch. This is one of the worst post office is as far as efficiency, and as far as attitude, I’ve ever seen in my life.
