A few weeks ago I used quite possibly the most disgusting toilet Ive ever had the misfortune to, ever. We drove for 3 and a half hours from Glasgow to Morecambe to buy a car, got to the garage and there was a problem with the windows, time was marching on and we were sitting in the car getting more crossed legged, eventually DS2 whos 8 asked first, the guy there showed him where it was, when he came back I asked him if its was ok - he said a "bit dirty" - this from the king of dirt who rolls about in the stuff and never notices it 
So I asked the guy if I could use it - the warning bells were there when he said "I dont think its suitable for a lady" (
at getting called a lady mind you) - by god he wasnt wrong, it looked as if it had been installed in the 60s in a tiny wee cubicle with a sink, and had never been cleaned since, a bit like 1 from A Life of Grime, crossed with Trainspotting with a bit of Kim and Aggie thrown in to!
I didnt think toilets and sinks could look so dirty, manky and filthy I really didnt. Of course I "hovered" - and managed to pee on the floor to - when I tried to clean that up with the "spit peas through" toilet paper (guess I was just lucky there was some eh) - the amount of dirt that came up that there was on the floor it need a mop and detergent, not a teeny bit of toilet paper.
And when I flushed the water rose to the top and flooded the floor again. 
Oh and just to make matters worse I was on my period - but there was no way on earth I was attempting anything else in that loo!
Needless to say when we left we found the nearest supermarket - and thank you Sainsburys in Morecambe - your loos are fantastic!!!!!!!
