Question 1 You buy a candy bar at the store and pay the cashier a $5 bill. You are mistakenly given a change from a $20 bill. What do you do? Question 2 My dad takes me to a lot of baseball games and always buys the cheapest tickets in the park. When the game starts, he moves to better, unoccupied seats, dragging me along. It embarrasses me. Is it OK for us to sit in seats we didn't pay for?
