Barfly Easter Egg - Charles Bukowski at the Bar

In Barfly with Mickey Rourke and Faye Dunaway, you can see a scene when they are in a bar and one of the 'barflys' is Charles Bukowski. Bukowski wrote the screenplay which is somewhat based on his life. The scene is late in the film and he is the one with the weathered face and has no lines or even credited in the movie.
