I was in the middle of a big job and was dying for a jobby all day but I held it in as best I could.... so much so that I was doing those weird internal farts where you fart within yourself and was crippled in agony until I could hold it in no longer....... I went in their ensuite (bathroom was out of action) and layed King Kong's finger down the bowl.
The smell was stripping the tiles of the walls and of course when I flushed it all the water rose up and it wouldnt go down......then Tony the customer came into his bedroom wanting to go to the toilet, he asked if I was in there and I said I would be right out.
In my panic I flushed again but the bowl was nearly full of water and it overspilt......I hadn't even wiped my ar$e and I was frantically mopping up water from the floor with the few sheets I had left on the roll. Then to my relief the toilet started gurgling and suddenly went down.....God the relief! because I knew Tony was waiting me out in his bedroom. I had to dry the rest of the floor with the bath mat and came out looking sheepish.
