- JHJohn HaganNov 22, 20251.0I always feel bad I have to wake them up to wait on me. And I think I saw one with a tattoo’I work for the government and I can’t be fired”.
- AMAli MitchellSep 8, 20255.0Very kind and patient clerk, there was no wait at all on a Monday afternoon and she was helpful with answering my questions about mailing an envelope overnight.
- TMTrop MarceApr 1, 20255.0Much better than the Boardwalk post office
- JGJohn GeigerNov 20, 20235.0This is a stand alone building with full retail services. It is in Riverside and is usually not too busy. Nice staff to interact with.
- TTTravisWTMCFeb 26, 20201.0USPS Discriminates the handicap!! I lost the use of my dominant hand in the Marine Corps the woman behind the counter refused to help me fill out the information on the shipping label saying I should have brought somebody to write it for me. I have never been treated with this level of disrespect by somebody with 2 good working hands what a disgrace to our Veterans!!!
