[TOMT] A Woman At A Dinner Table

I only remember glimpses but the dialogue and visuals basically were about how this woman was bottom of the barrel in terms of the dinner table she would be fed at. Apparently, your spot at the table was an actual indication of your status, so the further up you were (towards the "head" of the table), the higher up in status and the better your meals were. She was off tne table at the start, so she only got scraps. But through deceipt and fuckery, she got close to the head.

Anyone have any idea what show, movie or book this could be?

Thanks!
