I started doing it when I was pregnant last year because as soon as the water hit me I needed to go and after getting out that many times to find it was a teaspoonful I just started going in the shower. Now it's habit.
Nice one Talbot. Reminds me of the tale of two guys who had been out drinking and returned to one guy's flat. After a while the other guy said he needed the toilet. First guy told him that it was an outside toilet and as it was a cold night just to use the sink. After five minutes the second was heard to shout, "Have you got any paper?"
Let me rephrase that, I wouldn't sully my sink. I stayed in a hotel near Piccadilly Circus, the Regent Palace I think it was called, that had no facilities in the rooms. I used their sink.
My window looked out onto an inner area which didn't seem to be easily accessible. It was covered with wrapped up newspapers. Hate to think what might have been in them.
