My wife and I never tip. We give out "points".

For about the last 5 years now, my wife and I have been traveling quite a bit. And every time we go out to eat somewhere, we always give out points between 0-100. It's all in fun and games, but it can get quite competitive with the restaurant we choose. <br><br>We usually start at a 50. If the service is bad, it goes below 50. If the service is excellent, it goes above 50. We don't tip much. Usually it's around 10%. <br><br>But once we hit a certain number, we do something. For example, if we hit -50, we don't give a tip and give bad reviews on social media and Yelp. We also go outside the restaurant and write "bad service" on their window in washable markers. <br><br>If we hit 150, we give out a 100% tip. If we hit 200, we give out 100% tip and we give them excellent reviews on social media and Yelp. If we hit 250, we give out a 100% tip, excellent reviews on social media and Yelp and we write "excellent service" on their window in washable markers. <br><br>We also keep track of points for each city and country. We've been to over 100 cities in the United States and we have a list of who scored the lowest points and who scored the highest points. <br><br>For example, we found that Portland, Oregon has the best service, scoring an average of 67 points. That's a 17% tip. While the worst city is Miami, Florida, scoring an average of 41 points. That's a 9% tip. <br><br>For countries, we found that Iceland had the best service, scoring an average of 73 points. That's a 23% tip. While Costa Rica had the worst service, scoring an average of 28 points. That's a 2.8% tip. <br><br>It's all in fun and games. We like to travel and we like to give feedback to restaurants to improve their service. It's worked out well so far.
