If you ever head to China, especially the first-tier cities, you'll see that pretty much every restaurant gives you service that's noticeably better than most high-end spots in the US. The waitstaff are super polite, they'll go out of their way to help with just about anything, and they never get picky or judgmental with customers. But here's the thing—you don't pay one extra penny for all that nice treatment, because the servers are already getting decent wages. After putting up with rude service in American restaurants, it's honestly pretty baffling why folks are still so happy to tip extra.
