You're having a small dinner party.
You're cooking a fish dish that only takes 10 minutes to cook so you have it ready to go in the oven.
After sharing a drink and hors devours, you go to the kitchen to put the dish in the oven.
When the alarm goes off you return to take the dish out.
One of your guests has followed you into your kitchen.
They express how delicious the fish looks.
Next thing you know the guest has rinsed off a fork that was in the sink and "cut" a little piece off one of the fish steaks exclaiming, "Remember, this one is mine. I'm so hungry and it just smells so good!"
What do you say or do?
