You've had countless debates with him over fair bill-splitting at friend gatherings, where he would meticulously calculate each penny owed, down to the last cent. Your differences came to a head last night when you refused to split a bill precisely his way and now, here you are, stuck in a room with the very person you argued with, a sign reading: 'Settle your differences, or forever be locked in this stalemate!'.
