Having travelled widely in West Africa, I'm rather amused at the complaints about seats up or down. They don't have toilets like that there. They call such things 'chaises anglaises' (English seats). Over there, you squat over a stinking hole with several weeks' deposits staring you in the face. The flies are thick in the air and you gag while performing. There isn't any loo paper either, you go in with a small plastic jug of water and wash your rear end. It's unspeakably dreadful. So I never bother about a seat left up or down. I'm only too glad to own a 'chaise anglaise' !
