My mind interpreted their conversation like:
Sylverster: We need more Chalices
Myne: Nahh, bro, sorry no can do
Sylvester: But I have already accepted the request
Myne: So what ? Shame on you, go there and complete it yourself, what are going to do, demote me ?
Like, Sylvester is both a wise and unreasonable manager, wise enough to know that his staff is valuable and hard to replace, but unreasonable enough to keep constantly burdening them with tasks when they already have other tasks of their own to accomplish.
Myne "nu-uh" is the closest that we have seen similar to labor laws so far.
