I was at a dim sum place in SF Chinatown a few years back. While dining, a cockroach fell from the ceiling and landed on the back of my hand, which was holding a pair of chopsticks with dumpling in the middle. I jumped up, screamed, and shook the insect off. The waiters came running over to catch the cockroach, but they made no apologies to us, and none of the patrons seemed at all disturbed. As for me, I ate the rest of my dumpling, and we finished our meal.
