Etiquette is one of those things that’s meant to be on its way out. To attempt to bring some old skool decorum and manners into your daily life will cast you as a throwback, a dinosaur, or worse, if you’re a man, a rampant, unreconstructed sexist. Open a door for a woman? Sexist. Offer her the better seat in a restaurant? Sexist. Compliment her on her attire, and be prepared for an immediate visit from HR.
