Funny story. I couldn't hold it in a resturant in a small town outside of Shanghai. The problem was the door to the tiny bathroom. I stared at the door for 10 minutes wondering if I could hold it for the next hour drive to Shanghai. The factory owners were all sitting there at the table and I said excuse me please. I went to the bathroom with the "door" problem. As I entered the bathroom and saw the squatter on the floor I froze. It was the first squatter I had ever saw. But that wasn't near as big a problem as the door. The door was facing the entire sitting area and all the waiters were walking by it. AND... IT WAS A SEE THROUGH GLASS DOOR!!!!! I went and after 10 minutes of being in the bathroom (I must have drank some Chinese water) the factory managers walked up to the door and stared at me and asked me if I was ok. Ummm... I don't think I said another word the whole drive back to the hotel.
