Ernest And Davis' Working Relationship?

I was just wondering what kind of off screen relationship Ernest had with Bette Davis on the set of "White Mama"?

Did they each enjoy working with one another?

I know a lot of actors and directors, especially earlier in her career, found her difficult, but she did take certain young, new actors under her wing.

Hopefully, this was the case here!

I'd like to hear what he thought of her.
