Not really. I hope I'm not being overly critical, but "a weary customer" is pretty purple prose, and "intelligent enough to be aware of its affect" -- "affect?" C'mon. "Effect." If this were some other kind of writing, like a forum post or a blog entry, no problem, stuff like that wouldn't faze me. But I think you have to clear a high bar in quality if you're writing some sarcastic & condescending criticism of something else... especially when the "something else" is already aiming at a (relatively) highbrow audience. Otherwise it's not credible to me and not funny.
