Automatic toilets need to be banned. They waste water because they flush while you are still sitting on them (thus, requiring another flush). They vascillate between the extremes of not sensitive enough to movement (not flushing when you leave the stall), or too darn sensitive (thus giving your rear a second shower).
Gahhhhhh! Stupid toilets.
[EDIT: For those RevGal folks finding this post, I feel like I should have made this post more theological by using one of my fiance's favorite metaphors: Jesus as the heavenly toilet who flushes our sins away... :-)]
