Hi, All!   
      
   In "Good Omens" by Terry David John Pratchett:   
      
   +=====+   
       "Well, they (witches) blight crops," said Pepper. "And sink ships.   
   And tell you if you're going to be king and stuff. And brew up stuff   
   with herbs."   
       "My mother uses herbs," said Adam. "So does yours."   
       "Oh, those are all right," said Brian, determined not to lose his   
   position as occult expert.   
   +=====+   
      
   Is there any explanation why "occult expert" was used without "a" article?   
      
   Bye, All!
