This is an odd experience for Isabel, as she starts to see that Curzon is right: her white owners are willing to talk openly in front of her, without any acknowledgement that she may be interested in what they have to say. It’s also shocking to see the man request a refill so rudely—to Isabel, behaving in this way is unheard of. The fact that the man can grunt at her like this shows how privileged he is: he’s so privileged he doesn’t have to be polite to anyone.
