what is the punishment?

i come home tonight, going to fix some pasta, have the noodles cooking, get the cheese out, and go to my cabinet to get the black olives and it's not there. They were there yesterday, when I was looking for cream of chicken. Morgan has been home most of the day, because she now has the "sick as a dog" flu. So I say "morgan did you eat the can of olives". "Yea" was her reply. Who eats a can of olives. Do you set on the sofa, saying" hum....I sure would like a can of olives". Then I find myself getting very mad. It's not that a can of olives cost alot, but dude, you just don't eat a can of olives...you know. So i'm getting more worked up at her. How do I punish her for eating a can of olives? Sometimes I just don't get it.
