HE advice to Travis Bickle while standing outside the Belmore Cafeteria (Park Avenue South and 28th Street): “Look…you write a diary…right? You got a typewriter? Get one, get some typing paper and tap out a daily diary about your cabby life…not just the fares but your deepest thoughts…hates, fears, longings. And submit these pages on a weekly basis to the Village Voice and the Soho Weekly News or some other weekly rag. Who knows?…you could become a New York version of Charles Bukowski.”
