FNDN 201

Bobby decides that side hustles are dumb and continues to walk to his class. He is starting to run late because of the logistics of both gift tax and lottery winnings tax that they had to work through. At the doors of RNT, seconds before class starts, Bobby sees a man on crutches coming towards the door. He is far enough off that Bobby knows if he waits and holds the door open for him, Bobby will be late for class. Should Bobby wait and hold the door open, or run to class?
