In Japan, many ramen shops have no waiters. You walk in. There’s a vending machine by the door. You drop in coins. You press a button with a picture of a bowl. A small paper ticket comes out. You sit down. You hand the ticket to the chef. He starts cooking. Eight minutes later a steaming bowl of pork-bone broth appears in front of you. You eat. You leave. You never say a word. Not because anyone is rude. Because the system was built so a tired person at midnight can get hot food without performing a single conversation. The whole country quietly built a kindness for introverts and never told anyone that’s what it was for.
