Very disappointed for the Christmas holiday season. That I know of three of my cards did not make it to their destinations. One had a check in it. Shortly after the holidays another card with a check and it did not make it to destination. I don’t know why this continues to go on. We pay good money for postage and expect it to go through. OK it’s blamed on the sorting machine, people make mistakes and so do machines but how can so many of them happen. I did not receive any of the cards back. And I did not get one that was sent to me from a good friend in Alabama . What could the problem be, I wonder




Very bad attitude by the short, chubby woman at the counter of the Owosso, Michigan post office. Every time I go in there and happen to get her, I get a slight roll of the eyes and a do not care attitude. I watch her demeanor with the customers before me and they seem to be treated the same. The guy at the counter is usually polite and courteous towards me and others though. Put the impolite woman in the back room where she can act out her bad day with people who may accept her a little better.


the fact that you call this woman out as a short, chubby woman speaks volumes about you and your attitude towards women. You should be ashamed of yourself.
