This has just happened…
The gents toilet here at work is a small one urinal and one cubical room, with no windows. Most people leave the light on when they leave even though there’s a big sign on the door about being energy efficient and switching off unnecessary lights.

Stepping into the toilet, I realised that it’s not that dark in there, and I probably didn’t even need to turn the light on. Stepping into the cubical I locked it behind me and started to undo my belt…

…as the main door swung closed, rendering the room totally and utterly pitch dark. So unexpected was this, I completely lost my bearings, fumbled for the door lock, blundered into the sinks and had to feel my way round to the door and the light switch, all the while thinking “please don’t let anybody come in here now”

They're not sinks
they're basins.

They're not toilets
they're water closets.

Similar to a place I worked at.
Again, one trap and one urinal, with a sign to turn the light off.

The trouble is, you've be taking a shit and someone would come in, have a piss in the urinal then turn the light off on their way out.

If you were lucky you'd manage to call them back just in time, otherwise you've have to wipe your arse in complete darkness. I have trouble finding it with both hands when it's light.

"had to feel my way round to the door..."
...with your pants and trousers around your ankles? Please let it be so.

Haha, sadly not :)
I'd only got as far as undoing my belt, the door shut quite quickly

Shame...
...similar thing happened to me recently. I didn't know the light in the plush newly installed and rarely used toilets at work was on a movement activated time delay thing, movement inside the cubicle clearly didnt count. Shitting in the dark was a new and humbling experience.
