I usually go commando
I remember an embarrassing incident back in 2002 at Munich hotel. I had one too many drinks the night before, to cap off a weeks conference at the venue.
I awoke bewildered in the early hours in my hotel room and wanted to relieve myself.
I stumbled to the bathroom door opened it and walked through, it slammed shut behind, only thing was it wasn't the bathroom, I was now standing in the corridor starkers.
I tried to open the door but the latch was locked, so I had to make my way in the lift down to the reception to get let back in
