She is cheap when it comes to food .She does n't like to see leftovers on plates .She does n't want to clean up leftovers .None of the above choices .
What may be the reason for their grandma 's statement ?
She said " fine , but if you do n't eat that entire thing I ' m going to shove it up your butt ! " . No joke . Dear old Grandma said that . Which comes to another point , she was cheap too .
