So glad we don't have to put up with any of that BS here in Sweden. Sure, if a bartender has been giving you excellent service you might tip him/her a little something just to show your appreciation, but that's completely up to you. And that's how it should be. A tip should be a small bonus voluntarily given to someone doing a great job, not something demanded of you by people who get pissed off if they think you're not giving them enough.
Doesn't alcohol cost an arm and a leg in Sweden?
