The boxing ring (business casual is fine)
There’s nothing too unusual about discussing work matters over a game of golf or billiards, but sometimes fictional dudes need to serve up negotiations while beating the crap out of each other. Take a recent episode of Empire, in which record mogul Lucious Lyon (Terrence Howard) gets in the ring with a potential business associate to broker a merger and, perhaps unsurprisingly, ends up punching the guy in the face.
Meanwhile, in Iron Man 2, when Tony Stark (Robert Downey Jr.) meets Natasha Romanoff aka Black Widow (Scarlett Johansson), he doesn't exactly call off his boxing training in order to conduct his business like a civilized bloke. Rather, he lets her sub in for him and watches as she demonstrates her superhuman strength.
