Yu Fahai, 58, was carrying an urine sample in his pocket when the incident occurred. This was the first time Yu had ever flown. He was attending a TV awards ceremony in Shanghai. "The checker asked me what was inside, and I told her it was my urine. She said: "Urine? Drink some to prove it"," said Yu at his home in Chibi, Hubei province. Yu has filed a complaint against the airport. The security guard claims that the man's pronunciation was difficult to understand and mistook 'beverage' for 'urine.' Once the guard understood what the liquid was he apologized and made an exception allowing the liquid aboard because of Yu's medical history.
