This reminds me of a story about a top investment bank in Copenhagen (told to me by a long time employee but don't know the level of embellishment), one day there was a big company meeting down in the very expensive lovely cafeteria they had.
When people came in they looked up their names and gave them either a red or blue card. At the end of everyone coming in the person in charge stood up and said "as you arrived you received a red or blue card, the ones who received a red card have been let go, please get your things and exit the building."
