From Los Angeles Times:
The riot began with a customer’s complaint about her dinner.
“Waitress, there’s a tooth in my soup,” a Tibetan woman said indignantly.
Before long, a curious crowd of Tibetans gathered around the soup bowl. Restaurant owner Yun Sha came out of the kitchen and insisted that the offending item was just a chip off a lamb bone. “Let’s trash this restaurant,” Yun heard somebody scream, and the crowd proceeded to do just that.
Tables, chairs, a television flew through the air. Kitchen equipment was smashed with bricks. Soon the crowd had moved on to other Muslim restaurants on the same strip as terrified waiters and cooks scurried outside for safety.
