In-game chat messages sent by concierges have the yellow 'flair' if the player is in the room when the message is sent. The flair is not added to historical messages. E.g., in the screenshot below I entered the area at 8:51PM and all of johnr2's messages lack the flair.
Or here, I left the area and came back a moment later, and the flair from previous msgs is missing.
