Don't necessarily disagree with the author's point, but the story seems to not really illustrate what he's trying to say. Was he denied a job offer just based on his clothes? The way I understand the story the guy was pretty much saying: "man, don't feel obligated to wear slacks, nobody does, up to you". Was he told that wearing slacks was forbidden? Apparently he was explicitly told "Everyone wears what they want".
