Franco and Carla are walking down the street when they spy a paper bag. Carla is the first to pick it up, and discovers 20 one-dollar bills inside. "This is great!" says Carla. "Here; you take $5 and I'll keep $15." Franco indignantly huffs, "You're nuts! Either give me half or put the bag back down. I'd rather have nothing than take your lousy offer!" Which barrier to rational reasoning is Franco illustrating
