Paris Orly late 1990's.....
I'm taxiing in a Boeing 757 and given a late stand change. As I pull towards the new location a small van appears at about 100 kmh and a young energetic marshaller jumps out and starts vigorously waving me in. Because of the size and shape of the stand and the height of the 757 cockpit he has to start walking backwards to keep me in view - he keeps backing up until he disappears through an open door in to ground level office!!
I stopped - not for safety reasons. You can't taxy and laugh hysterically at the same time.............
