I spent quite a while cleaning the bathroom yesterday morning, which made me even more annoyed, although I always keep the toilet clean...
A friend came round for a few hours and when her DP came to pick her up he went to use the bathroom and was there quite a while. When I went up there 10 or so minutes later I was hit by the most godawful stench, although to be fair to him we haven't any air freshened and he had opened the window, but oh my god the state of the toilet bowl! Skidder central. It was absolutely rank.
Surely it's common curtesy to flush a couple more times and pour some bleach down to try and get rid of the evidence if you've had a massive skiddy shit at someone else's house (and in fact your own house!) We have one of those toilet duck brushes with disposable heads which is in the cupboard so he couldn't have known it was there but the bleach is right next to the bloody loo!
