I’m like 99% sure the Gotham Elite’s social customs are fucked up because Autism-in-Human-Form Bruce Wayne was just so fucking tired of high society’s weird and incomprehensible (and frankly ableist) social etiquette that he went full Virgin Mary About-to-Invent-a-Major-World-Religion, said “oh haven’t you heard?” and just started making his own random social rules. Like who’s going to stop him? The other elites? The dinosaur CEO’s? He’s richer. He hosts the better parties. He could tank your business in a weekend. So when he says “Weird passive aggressive fork language is out. Having a different utensil for every different food texture is in,” you use a different utensil for every food texture. Now when foreign elites visit Gotham, they have to learn a completely new set of social customs to fit in. It’s like a cult, but the cult is run by the most influential man in the world and Gotham’s personal Jesus. The followers are more likely than not mafia bosses named after a bird. You will be judged. There’s a test. Yes, you do get brownie points for being nice to the servers. For the love of god, stop making so much eye contact. The cloth napkins are folded into little ducks. Welcome to Gotham.
