An email had to go around the other month because someone had literally sprayed sh1t all over the inside of the lavatory door. The toilet was untouched. Exercising my Hercule Poirot-like little grey cells, I could only conclude that some poor chap had been caught with une crise d'estomac, got into the lavatory, pulled down his trousers, but failed to turn around and sit down in time.
However, that doesn't explain why he would then have left the lavatory in that condition, presumably cleaned himself up and then gone and resumed his seat to work again. Terrifying what human beings are capable of doing, isn't it?
