The only thing I can figure is that she put a really big flag in a room that wasn't hers alone but was one that she shared with other supervisors. I cannot for the life of me think of any other reason why a flag would be offensive unless you came into some little room that shared with five other people to find a 3 x 5 foot flag taking up so much of your space. On the other hand if it was just there for the Memorial day observance you'd think that they could have endured it for just a little while.
