I've heard people say Asian people don't tip either (as there's also not a culture of tipping in Asia). While we're Asian American, we are aware of that stereotype so we always tip 20-25% for good service. Even when we had poor service, we'd tip the minimum 15% so the disgruntled server doesn't take it out on the next Asian American diners.

I wish restaurants would just move to a service charge model included in the bill so servers get a decent living wage.
