As a dutch guy i find tipping really strange.
Giving someone a bonus because they write down my food order and bring it ??
Some (stupid) states allow restaurants to pay employees less than minimum wage (which is already low in most of said states) if they earn tips that equal or exceed the minimum wage. There are many people who essentualy survive on tips. So if you come here and refuse to tip (even if the service is good) think about the kind of living situation your server might be in and how crucial tips may be to them. It's part of the culture to be generous to these people who are doing a job that you probably don't ever want to do. I enjoy tipping someone who went out of their way to provide great service because I know it helps make their a job a little more tolerable and ultimately helps improve the quality of their life.
So yeah. Tipping isn't a bad thing unless for some reason you hate the idea of generosity.
