u shld have wink at him n lick ur lips
after he gesture u to go inside the cubicle wif his erected pecker,
go in wif him n make sure his pecker doesent erect anymore
ok la, u shld have really inform the authorities
if they dont bother jus dial 999 straight, they have to come
they might not able to do anything to him but at least he will
think twice b4 playing such stunt again
better still, take picture n send to stomp !
