I was replying to what you said. His hyperbole regarding unintelligent customers was the behavior that was called out as not nice, professional or intelligent.

I was replying to what you said. His hyperbole regarding unintelligent customers was the behavior that was called out as not nice, professional or intelligent. His piss-poor use of hyphens (see what I did there?), however, isn't hyperbole. Hyperbole is a rhetorical device (and the greatest thing ever!), and unless he intended to evoke an emotional response in his readers by their incorrect and non-poetic application, it's just bad form; Being from the UK has bugger all to do with it.
