Who is Lou from Notes of a Dirty Old Man and what is their importance?

Lou appears in section 32, and appears to represent the acquaintances of Bukowski throughout much of his life. In the story, Lou plans to rob a rich man in the parking lot with Bukowski's help, and they are to split the money. When things go awry, however, Bukowski finds himself being beaten and robbed by Lou instead. Throughout many stories, Bukowski tells of unnamed friends such as Lou who take advantage of Buowsiki's abilities or talents, only to turn them against him as needed. While not vital to the storyline, the character does portray the reason behind Bukowski's lack of companionship and trust in others.
