Toilet Training Required

Above is a sign mounted on a toilet wall in Chiang Mai, Thailand. It is clearly a guide to proper use of the toilet. The meanings of the top four are obvious; the last two less so. I suppose the bottom right hand image is their to remind us that a bidet is not to be used as lavatory; the left hand image, which appears to show a very optimistic angler, is baffling. The East is not called 'inscrutable' for nothing.
The one I wish to draw attention to is the one at top right, which shows a man urinating into a toilet pedestal. It is a graphic which could profitably be displayed in British public toilets, as the practice of weeing in toilet cubicles - often without raising the seat - is rapidly becoming universal. I cannot say what caused this flight from the urinals; whatever the reason, it is a slovenly, unhygienic habit which, apart from anything else, makes the cubicles unavailable for their proper use. God knows what foreign visitors make of it.
