RE: Alice has 5 ice cubes, Bob takes 3, how many ice cubes does Alice have left for her afternoon Thai iced tea?

Hi. Obviously, since the question is read, it is perceived that there is a trap.
Mathematical models are fabulous but largely based on ideal situations.
All human beings are absolutely different. We may have similar reactions to certain stimuli but that cannot predict human behavior.
Very interesting observation and the warning you make in this post. Regards @blocktrades
