Encountered a cute crepe truck this morning that accepted bitcoin (on-chain only). So I hooked them up with a copy of my book and got them to download nostr:npub1ex7mdykw786qxvmtuls208uyxmn0hse95rfwsarvfde5yg6wy7jq6qvyt9 to learn about the lightning network. They were psyched to learn there’s a faster, cheaper option. ⚡️🙌
