Let say friend A, a student and friend B, working full-time,
went for a lunch together. After the lunch, friend B paid with his
credit card as it was easier this way.
So A decided to pay B by cash. Let say A's meal cost abt $11.70,
but he only had 70cent coins and 2 pieces of $10 notes. So A gave B
$10.70 first and asked B how to settle the last $1. A had only 1
$10 note left and B did not have $9 change.
ok here is the question. Let say you are the friend B, what will
you do?
1) Forget about the last $1 since you two are friends.
2) Ask A to give you his $10 and you returned whatever change you
have to him(assumed you had about $7 or $8 change).
3) Insisted A to buy something else in order to have small change
to for him to return you back the $1.
4) Other actions.
