Postal Locations

Are post offices no longer government entities? The Lakeside Oregon post office had a flag that was a total disgrace. When a disabled veteran made a comment about this to the postal worker, she not only asked him to take it down for her, stating she didn't know how, but she also made the comment that she didn't know when a new one would be put up because she had to pay for new flags out of her own pocket. Is this true?? I thought our government supplied new flags to our government business. It has been over a month now since the Lakeside, Oregon post office has had a flag flying outside it's building. No American pride there!!
