How do the delta twins react to the savage's pushing through?

At the beginning of the chapter, they react with a bit of
annoyance, but nothing too bad.  They all react the same way, of course.  The narrator
says that they are all saying pretty much the same thing.  But there are only two voices
-- they are all just two sets of "twins," it seems.

As I
say, they are only slightly annoyed, asking John "Who are you pushing? Where do you
think you're going?"  But when the soma comes out, they forget about John.  It is not
until he stops the soma distribution that they really get angry.
