That's how tips should be. Where I live it's the same probably even more on the no-tipping side. I'll leave a tip when you've gone above and beyond (which is rare, service here is "sober" to put it gently, which is fine, it's somewhat efficient but just not personal at all).

Or, if you're the Italian head of bar at the fancy restaurant I took my wife out for anniversary dinner, got seated at a bar table and then you proceed to both entertain us, rock the venue, swap out our inexperienced waitress for the maître d'hôtes, and pour us free drinks on the sly, then you better be sure I'm slipping you a 20€ on the way out. That stuff is extremely rare though.
