We are on dining plan 4 adults and 1 child. But I am not a very big eater and may often share with my 14 D.D if we are both not very hungry or sizes too big for us both, too much food. That would leave us some extra T.S credits, and my DD9 isn't always going to be satisfied with childs Menu. So, I thought she could use some of my T.S for herself if she wants a Adults Meal once or twice. How do the C.S know that we are using Adult T.S for her and not just trying to pull the wool over their eyes?? How do we do this or can't I??
