The key part of that is the line about services and tips. Just being a generous tipper gets you better service, and specially if you are a regular at the same restaurant or bar. 20% by default with an occasional bump up to 25% in tip gets you remembered and the servers get to know you. I've had such a good relationship at some of my regular restaurants to the point where I once had ups deliver a package to the bar for me when I was out of town. Other places, the staff starts comping your drinks. My best one was the manager at a restaurant giving me a blanket 20% discount on anything I buy (I tip at least 25% after they put in that discount). In the long run, you get better service if you pay for it.
