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.
Magnificent Bastard: Ricky Roma, who artfully manipulates a potential customer while riding his hot streak.
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 characterising pretty much everything wrong with corporate America) is used a motivational tool in workplaces.
The Woobie: Shelly "The Machine" Levene. In spite of the way we can see how sleazy he is by his sales tactics, he's such a sad-sack with a sob-story that we can't help but feel sorry for him.
