- a poor man and a rich man are going to work when they each see a dollar coin on a sidewalk. Which of them would bother to pick it up?
- a poor man and a rich man are both drunk after spending a night at the bar. Which one would take a $50 taxi home, and which one will take a bus for $5 (you have to wait 15 minutes for a bus).
- a poor man and a rich man are both hungry and walk by a restaurant for rich people. It would take an extra 15 minutes to walk to a crappy diner for poor people, but a lunch costs 5x cheaper there. Where would each man dine?
