My picky eater!

My daughters visited grandma one week when they were little and came home with
the idea that they could come to the table and order whatever they wanted to
eat. I told them that was a great idea, let me get a piece of paper and write
down what they wanted. Thrilled with their success, they named food after food
(except what was on the table). I wrote it all down, got my calculator and
tabulated for a few minutes while they puzzled over what I was doing. "According
to my calculations, that'll be four dollars each, please" WHAT!!! I then
explained that if you want a special order, you have to pay for it, just like
you do in a restaurant- that put an end to that nonsense!
