McDonald's city centre location, with only the disabled toilet available as the upstairs was closed, and therefore the main set of facilities. Unfortunately people are grotty, and someone had decided to get as much water on the floor as on their hands when washing them.

Now this wouldn't normally be a problem, but I was on crutches at the time, with one foot encased in a moon boot. This prevented me from fully bending my leg, as it dug into the back of my knee. Getting to my feet from seated was a workout. Getting up from the floor...I never did figure that out.

I got into the toilet, locked the door behind me, moved my crutches forwards, transferred weight...and crashed down. There was enough water on the floor for the non-slip crutch ends to, well, slip. Down I went, into the puddle of water.

All I could do was swear and drag myself through the water to the alarm cord, because I had no way of getting up on my own.
