    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.

    Something has changed with the service... several months ago all was good. Today she refused to scan my packages... the person filling in for her the last several weeks had no problem doing it. The PO on Vivion (when they are open) has no problem scanning packages and neither does the NKC PO. This one happens to be on my route home... Must be nice to refuse to do your job and still get paid.

    Every time I've entered this post office, the staff always has an attitude of gratitude. The clerks are usually professional and very quick. Typically, I am in and out within minutes!
