Games with Dad

Jeff was playing cash register with Conner the other day (one of Conner's favorite games) and was buying many things from Conner's store. After Jeff would pay he was trying to get Conner to figure out how much change he should really get back. Dad decided it would be a good learning game. After a few rounds of this Conner says firmly "Dad, please sit down. You will get what I give you." in response to Jeff trying to tell Conner that he should only get $1 back from $5 instead of $24.
