Hang with the boss in the stadium luxury suite.
Rule #1: Dress like you belong there. For weeknight games, work attire is fine, though you can't go wrong with jeans and a blazer, suggests Petra Pope, senior vice president of event marketing for the NBA's Brooklyn Nets. Rule #2: Don't talk shop (or order a cocktail) unless the boss does first. Rule #3: Don't pretend to be a die-hard fan if you're not.
