These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crosses the Line Twice: The constant berating is nothing if not unique, which makes some of the insults stinging and hilarious, such as Roma's disdain for an Indian client, stating that he was so stubborn, not even the Indian gods could get him to sign a deal.
Levene tries to provoke one of these at the end when, inspired by Roma's speech above, he finally stands up to Williamson, but it's ultimately subverted: in his eagerness, he lets slip something that gives him away as the person who robbed the office the previous night. Williamson picks up on it and spitefully uses it to destroy him.
Ho Yay: Roma's seduction of a customer isn't subtle.
Misaimed Fandom: Not only is the film loved by the very Salesmen it sets out to destroy, but Blake's scene (which is intended as characterizing pretty much everything wrong with corporate America) is used as a motivational tool in workplaces. Of particular note is a Cracked.com article (see Memetic Mutation above) where the author pretty much uses the scene to describe how one might become a "better person", when David Mamet has openly said he intended that scene to show what was wrong with rampant capitalism and cutthroat sales tactics.
One-Scene Wonder: Blake's scene in which he completely berates the office staff for their failure to perform. Especially notable as it's original to the film adaptation.
