Eating but not eating food

Ever just watch a restaurant scene in a film and see how much food the characters actually eat? They play with the food, they take a drink, maybe a fry, they might eat a fry but they usually just point with it. Sometimes the characters take big mouth fulls but that's normally when the dialogue is about the food.

Only in Twin Peaks do characters stuff a whole donut into their mouths and nobody says a word. Twin Peaks makes me hungry.
