Tipping service workers is not a thing where I live, and anywhere it is, paying service workers fairly in the first place is always a better alternative.
Copyright just isn't a well thought out system. How can somebody "own" an idea? It doesn't make any sense, and doesn't have any solid foundation because it was originally designed as a form of censorship, not to stimulate people to create works. If it was designed for that then it's failed miserably, because in its current state, copyright only exists to serve massive organisations that can afford to fight anyone over anything, often regardless of whether or not their claims are legitimate.
