I once had to call the downtown Nashville public library when the US flag was flying at half staff and tell them that the Tennessee flag should not be flown at full staff beside it. They acted very puzzled, but soon after someone came out and lowered the Tennessee flag. You would think that government paid library workers would know the rules.
Yes, you would expect them to know. LOL If not, they certaily have a building full of books and at least one will have everything they ever need to know about proper flag etiquette.
That reminded me of one I missed today, and just took care of by a phone call. The Wal Mart had lowered the American flag, but not the Tennessee flag. Made the call and the man said he would have it lowered.
