Most of the time my human goes food foraging, she fails to include me. How should I best punish her?

Dood...why would you WANT to go out foraging for the foods? That's WHY you have her! To get it for you! Now, if what she's bringing home is unacceptable, then barf it up all over her pillow a few times and she'll get the hint. But really? You don't want to go out with her when she's getting the foods. There are sticky little people out there. Grabby sticky little people...
