Voice of the airport

In an earlier post you could already read that I had some strange experiences at Chinese airports.
Last year I had a special group travelling with me through China. This group consisted of older couples and a few singles from the same Christian organisation. The group started their trip from Shanghai and had to continue to Xi'an after a couple of days sightseeing in Shanghai.
I didn't know the group very well yet the day we had to take the flight to Xi'an as we were only 2 days together.
We arrived well on time at Shanghai International Airport to grab our flight but the flight was delayed. Which is normal in China, a flight arriving on time must be a miracle. After checking in the suitcases and receiving the boarding passes we passed the security check and headed for the boarding gate to discover that the plane had some delay. The ground staff assured me it would only be delayed for 1 hour. So I gather everyone around and told them they could leave their hand luggage near the gate. I would watch the bags while they could have a walk around and look at the shops at Shanghai Pudong International Airport. I also instructed them to be back on time (1 hour later).
As promised 1 hour later the plane arrived and we could proceed to board the aircraft. Everyone from the group picked up their luggage and got in the plane. I saw that one backpack was left behind and according to the luggage tag it belonged to Miss X, a single lady in the group.
I asked the group where Miss X could be and they revealed that she had a drinking problem and probably was sitting in a bar.
I got a bit worried as we had to board the plane immediately and asked the ground staff if I could call for her through the microphone system of the airport. They allowed it and I prepared my best voice to announce solemnly that Miss X was asked at the gate quite urgently. The whole of Pudong Airport heard this Dutch announcement.
I waited for 10 minutes and Miss X didn't show up. The ground staff urged me to hurry up as they wanted to close the gate in a few minutes. I gambled and took a choice and ran through the enormous hall of the airport looking in all the restaurants and bars around. I finally found Miss x sitting in one bar drinking a beer and looking at me as she was from another planet. I explained her the situation and finally got to her. She looked as she waked up from her trance and started to panic. We both ran to the boarding gate, where the staff was waiting for us. We got on the plane and entered the plane as the last passengers.
So that was a close call.
From then on I knew Miss X's problem and watched her carefully.
She didn't disturb the trip any more but we had to organise some "toilet stops" quite frequently for her.
