Fine Dining full of waste?

Ok what i am learning is for Fine Dining at college, i have been learning cuttings n stuff. When cutting, the lecturer teaches us how to prevent wastage when doing it, for example cutting 1 whole carrot into 6 different cuttings without wastage.
But honestly, i think Fine dining has MORE wastage.

Wasting part 1) I have butchery classes every alternate thursday and, yes more wastage. When u cook a duck dish like a duck stew for example. Refer to pics below, You would use a whole duck n no wastage right? what he teach is, cut off the neck, wings,and dump it somewhere first. What he asked us to do is cut off the thigh and breast. After doing that, he asked us to cut the duck breast and discard the whole carcass with the drummet n extra edible fleshes with it. And then comes to a rabbit, He also told us, this is the only rabbit we will see for our entire 2 years diploma. All the cut is the tenderloin of the rabbit and the thighs of it. And he threw the body with the front legs attached. What a waste, + i asked the chef, can i take back the rabbit? sarcasticly, he said can can but dun use my plastic wrap or watever to bring it back ok? zha dau, too bad the place im staying doesnt have a fridge to use. otherwise i will bring alot of stuff back home n cook.

Wasting part 2) Im a person who doesnt like to throw away uneaten foods, I mean seriously, if u imagine urself living in poor countries without food, then u know lah. I went for commie which basically we go n help term 6 seniors to cook( mostly washing n cutting) IT was dam fun but the drawback is, more wastage, i mean alot. My senior, kent he was cooking beef, and duck breast, he n his mate allison, cook the meat first, then both of them made mistakes, allison made her huge duck breast into duckling breast in which the lecturer mentioned, n she putted it ontop of the cooking counter. Kent pula he left his beef into the oven too long and it was overcook la, i tot hes gonna cut it n serve, but he cutted it abit n throw it into the bin -.- zha dau still can eat ma diu. I was thinking " oh wat the fuck? give me eat better la". at least allison gave me n my classmate ching, to eat her overcooked duckbreast, dam nice n crispy. Another thing is, after sending their dishes to their lecturer to test, some wouldnt eat n will throw it away, so waste meh?. Only a few would bring back their dishes to eat.

Now i plan to bring tupperwares to class n if got extra foods, i bring back makan. Dowan waste money.
