I found several things wrong with this picture, but to me the most obvious was the assumption that everyone was going to pay their bills and get out of debt. In the real world (if someone was stupid enough to give the clerk $100 to view the room in the first place), out of the other participates,some would save the money ,some would spend it and others would use it to get into more debt and none of that could happen within the timeframe of examining a hotel room
