Sure, it's a habit leftover from war time, but girl please. How many of you have ever been embarrassed when your Korean Mom grabs 30 napkins instead of the 3 she actually needs? When you open the kitchen drawer at home is it filled with packets of ketchup from Mcdonald's and sauces from Burger King? Once my Grandma gave me a Mcdonald's ketchup packet from so long ago, the contents looked like melted chocolate. Sometimes a Korean Mom will make her child steal napkins and ketchup from an eatery in her name. God forbid you only bring back 2 packets of sauce. The Korean Mom will make you return to the counter to retrieve more and you will have to make an excuse like "We dropped the other ones", to defend yourself from the annoyed service person.
