>For wet floors, I have yet to see “Caution” or “Slippery When Wet” signs. The last one is particularly obvious, isn’t it? Someone could easily write “No Shit” right below it.
I suppose Chinese people can see that the floor is wet and that running across it at full speed or careless walking may result in disaster. So there’s no need for such hand-holding.
Though I still wonder how many broken necks have occurred without this Western comfort.
