Bateman confesses the murders to his friend on an answer machine, then at the end meets him at a gathering. The friend doesn't believe any of his confession as someone said they'd seen Paul in a restaurant. Making the point that they're all so superficial that no-one really knows or cares who anyone is. Or it's all in his mind..."This is not an exit" on the door behind Bateman shows he stands as a symbol. Bateman is a satire on American Values. He is victimised by the "yuppie era".
