One of the best ones I've seen, on instructions for a hot air paint stripper.."Do not use as a hair dryer" Can't believe anyone would be daft enough, also on those little bags of silica you get in camera boxes etc the words "Do not eat" ...alB
would consider the public too stupid to realise the floor in a shower may be wet..."
Actually, large numbers of 'the public' are very stupid indeed, and would jump at the chance to claim a bit of compensation from someone if they slipped on a floor when they hadn't been warned.
By displaying the sign the council has removed one possibility - that someone could make the allegation that the council was negligent in not warning people. If you slip after a warning you have only yourself to blame. Stupidity levels can be judged by the case of the woman who successfully sued McDonalds because she was scalded by hot coffee, and the company hadn't warned her it was hot. She was almost unbelievably stupid in gripping the coffee cup between her thighs in a car, and attempting to remove the lid, but she was awarded a considerable amount in damages (subsequently reduced by another court), and McDonalds had to put a 'warning - coffee may be very hot" notice on its cups.
