A fair use excerpt might shed some light on the reviewer's credibility:
"Like Bukowski, Chinaski worked for decades as a mail carrier for the U.S. Post Office."
First off, that doesn't make any sense, and Buk was only a letter-carrier for three years. So he cites the usual casual Buk stereotyper pastimes of drinking, gambling and womanizing and blah, blah, blah, but at least he liked the book.
So come on. You've got to admit that the scene where he eats the snails with Barbara Frye and says "EVEN PURPLE STICKPIN HAS AN ASSHOLE!" is pretty funny.
