One of the two waiters of the dining car of the Trans Mongolian Express
This very friendly man wore the same gray T-shirt for five straight days and together with just one colleague he worked more or less all day and all night during those days.
Note: The waving of this man might look a bit strange, but that is because of the timing of the photo. It was a nice greeting gesture after our visit to the dining car.
The seats in the back are being occupied by trading goods of the Mongolian traders in the train.
