I don't know the name of this song in the movie "The Pianist"?

I recently got The Pianist movie soundtrack, and loved all the songs/pieces on it, but it didn't have a song I really liked from the movie. This song is played by Spzilman when he is in the Jewish bar, and it's just a calm nice little background piano song. It's the song that he plays when the man comes up to him and asks him to stop playing for a second so that one Jewish man can flip his coins and see if they are real or not. Does anyone know the name of this song/piece? It might not even be a real song but I don't know...P.S. only people who have seen the film or know about the composer Chopin answer please.
