I happened upon this story today: http://www.myfoxal.com/story/15681535/olive-garden-apologizes-to-kiwanis-club
It appears as though an Olive Garden employee refused to let a person bring an American flag into the restaurant. They were having a meeting with the Kiwanis Club.
Olive Garden has since issued an apology. The comments I am reading on that story seem to not care about the apology and say they won't go to Olive Garden ever again.
When things happen, even if they are indeed a mistake, it is very hard to undo the damage that has been done.
