I'm reading a short story "Getting rid of Geogre" by Robert Arthur. In story, there's a conversation that I can't understand (the bold part). The context is: Laura Layne is the famous star of Hollywood. And Dave is the head of publicity which Laura is working for. He said to her that there's a new reporter wanted to make a quick interview with her. And she said:
"I'll give him Three-B. Now send up Harry Lawrence with a drink, and then I'll be down."
