My sister used to be a cook for two one-star restaurant and a five-star hotel (now in a better paid yet more laid-back job). Your assumption is normal (i had the same) but its false. Even when they reduce some leftovers for sauce/juice, they trow away a lot of food to make it look good. And its even worst for the "grande cuisine" where they throw away multiple dishes when someone at the table goes for a piss and the waiter forgot to tell the cooks. Maybe in fast-food or with bar cuisine this is not the case, but from what i know, they are probable the most inneficient users of food.
