Years ago I worked in an office where there were two bogs on the ground floor. One was through a couple of coded security doors, which I had access to, but frankly couldn't be ersed. They were separate traps.
The other had two small rooms - one kitted out for disabled users, the other available to both sexes. It was much more conveniently located.
After a particularly heavy night out, which included a memorably vicious Indian meal, I dashed, slightly panic-stricken, to the safe confines of the multi-sex loo. I have to report that what followed was near unspeakable, and I will not tarnish the offices of this fine forum by attempting any significant analysis or description. All I will say is that an exorcist, and not a cleaner, would have been necessary.
Anyway, when the deed was done, I staggered to the sink, and washed up. I faced the gaunt figure in the mirror, who stared back at me remorsefully. I noted the lack of air freshener, and opened the door.
Immediately outside the room were 3 women who were on a training course (10 min break). They were all known to me, and people I would subsequently see and work with on a regular basis. The first said "hello" and stepped into the room. The door closed and a clearly audible "jesus christ" was uttered. The wake of the abomination was following me as I left and the other two woman looked at me with pity and distaste, and turned tail - heading for the less conveniently located convenience.
I apologise for the long post. I've lived with this shame for 15 years.
