Ugly Gryphon Inn: Local DragonsExpansion

From BoardGameGeek:

You've handled plenty of rowdy customers in your time, from monks and mages to giants and goblins, but there's one thing you've never faced: the mighty Dragon. Now your humble inn has drawn the attention of an ancient wyrm. Pay close attention to who leaves and who stays: if your departing Patrons irritate the lurking Dragon, all your hard work is sure to go up in flames! Each game using the Local Dragons expansion adds 1 of 3 possible Dragons to your Inn. As Patrons leave, check their symbols to see whether they provoke the Dragon. If the Dragon is sufficiently provoked -- two matching symbols accumulated -- you'll lose the game.
