My SO had a spicy chicken dish, and he soon ran out of soda. Our waiter never came back -- not until long after we were finished eating. He dropped off the check and left without a word. Not one refill, nothing.
I'm a generous tipper. Usually around 30%. I was baffled at how badly we'd been neglected...I mentioned it to a friend of mine, and she said, "Oh, it's a Chinese thing. You didn't stiff him, did you?" Of course I stiffed him. And why would it be "a Chinese thing"? O.o
