    I 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”.

    Very 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.

    This is a stand alone building with full retail services. It is in Riverside and is usually not too busy. Nice staff to interact with.

    USPS 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!!!
