My family were regulars at a local Chinese restaurant for years.
One of the dishes we usually ordered was Peking Duck.
First, the waiter brought out the cooked duck on a trolley and carved up the duck, arranging the cut pieces of duck meat on a dish. The duck meat, pancakes/tortillas, sauce, and condiments were placed on the table.
At this point, the duck carcass was taken back to the kitchen to be prepared for the second dish - this restaurant just carved up the duck carcass and brought out the cut up duck carcass as a second dish.
My family were never that interested in the remaining pieces of duck since there was little meat on them.
Instead, my dad would ask the waiter to be given the duck carcass to take home so my dad could prepare the remaining duck meat his way (call him old school).
One time, after the Peking duck was presented and my dad had been given the duck carcass for later enjoyment, another waiter came out holding a dish filled with cut up pieces of duck.
But OUR duck that we ordered was in a bag near my dad.
The waiter claimed that the duck dish was for our table.
So where had the duck for the dish come from?
