The owner used to work there as a waitress and now owns it because it was her dream to own the restaurant. The previous owner ran the restaurant into the ground and she took over and didn't change a thing.
Tatiana's mother put all her retirement savings into the restaurant, and Tatiana's sister put her house as collateral. Tatiana put $1,000 into the restaurant.
She tries to appear sympathetic, but Ramsay is already stating facts as they are presented and she finds herself portrayed as the uncaring villain, with her living expenses covered by the place, while the sister and mother get nothing.
Here's a scene that's about to go to hell immediately: Gordon is ordering. The waitress is warning him about the lasagna. Tatiana, the owner, is already pissed off at her own waitress. Ramsay tells the waitress to not spoil the surprise about the lasagna.
