I had an experience in a men's toilet once too, amazing really.
Anyway, as I opened the exit door slowly, towards me, I was astonished to find a hand reaching for the door knob on the other side at the same speed as I opened the door. The other guy had this bewildered look on his face as the door handle just did not occupy the space he thought it did. His hand and body kept following this door knob right up until I had to catch him to prevent him going face first into the wall by my side, as he had completely lost his footing. I used the think that this kind of leading was "ki", but now I no longer think so.
