This post office is the most unprofessional and rude that I've ever experienced. The clerk had loud music playing, a dog running around the back, and a cluttered workspace "decorated" with unicorns, mermaids, and all kinds of junk. She was rude to some of the customers, including a man who spoke with a strong foreign accent and couldn't be understood with his mask on. Rather than trying to help him, she dismissed him with a rude, "I can't understand you" and he left without being served. She avoided answering some of my questions and as I was leaving she shouted an insult to me. It was unbelievable.


Great Efficient . service . One of the fastest clerks I’ve ever seen .
