Here's a link to an interesting article about some important writers having dinner: Ernest Henmintway, John Steinbeck and John O'Hara (Butterfield 8, Pal Joey, From the Terrace.) The shabby behavior of Hemingway is reflective of his stature relative to Steinbeck. Hemingway was much more favored by the eastern literary establishment, but his work isn't standing the test of time near as well as Steinbeck's.
Steinbeck years later wrote in the manuscript of East of Eden: "In my time, Ernest Hemingway wrote a certain kind of story better and more effectively than it had ever been done before. He was properly accepted and acclaimed. He was imitated almost slavishly by every young writer, including me, not only in America but in the world. He wrote a special kind of story out of a special kind of mind and about special moods and situations. When his method was accepted, no other method was admired. The method or style not only conditioned the stories but the thinking of his generation. Superb as his method is, there are many things which cannot be said using it. The result of his acceptance was that writers did not write about those things which could not be said in the Hemingway manner, and gradually they did not think them either."*
