NEVER - I hate public toilets anyway.
Dp walked into the mens at the station a couple of weeks ago to find a 15 yrd girl about to be raped. He was tipped off by her friend running out crying and there was a "lookout" ready to warn his friend.
Not into big time violence but DP is when it comes to predators - he glassed the lookout and totally wiped the floor clean with the dirty, horrible bastard who was about to get his way.
