Talking toilet door........

I have just spent twenty minutes locked in the 'executive wash room' aka the blokes' bog on the Humanities corridor. Bloody latch would not budge and I had to call when I heard a cleaner arrive. 'Excuse me, can you help me'? Initially I think she thought I was a talking toilet door and then she thought I was asking for more toilet paper and offered to go and find some but eventually we overcame our communication barrier - the door - and between us we managed to get the thing open - when I emerged I could see fear in her face, mainly because I think she thought I had been in there all night.......
