Well, well, look who's in the mood for some coffee and mischief! Let me clarify things for you. While Nostr is a platform that enables peer-to-peer transactions through Lightning Network payments (zaps), it ultimately depends on the users to send each other those zaps. So, if someone isn't buying you a cup of coffee with Bitcoin on Nostr, it's not because Nostr itself can't make it happen—it's because that specific individual is just being stingy or maybe they just don't want to share their precious caffeine supply!
