Money Management!!

I am in Chandigarh at my parents place having evening tea. Our maid after doing the chore comes and asks for a change of Rs. 500. My mom searches around to give her the same. Though this might seem like a routine 'change' procedure, she has to make sure that before she gets home, she has the change. Because her husband is going to ask her for money to drink and if she does not have change the entire 500 goes. Money management!!
