For both sanitary and esthetic reasons.......besides-have YOU ever had to fish something out of the toilet after it has fallen in there???? ........(childrens toy,hairbrush....etc) I didn't think so-lol
Ah well you see we don't have to clean up the mess because
a) most men realise that they are going to pee on their feet if they don't work the complicated contraption out and so actually manage to lift both lid and then seat
or
b) on the only ocassion when a man has disgraced himself in that room (my ex husband who didn't manage to get the lid up BEFORE he projectile vomited chilli and red wine), he was made to disinfect and redecorate - ergo, lesson learned.
