Just by way of balance, I have experienced Tatiana and thought she was excellent. As far as I was concerned she went above and beyond for me.
I will also say that I really don't like naming and shaming on this message board. The crew member has no way to respond to criticism. And it's unfair because of that. If I have something negative to say about someone I would never post their name, but address it through other channels. I make my own mind up about someone when I meet them, not rely on tittle tattle on an anonymous message board such as this. Bad form in my view.
