Wet Fish

[Chipchopper]

I've noticed that a lot of supermarkets etc, put out yellow warning cones, if the floor is wet after cleaning or customers have trod snow in.
Often these cones have a fish symbol on the to warn that the floor may be slippery.
wouldn't it be more appropriate to have a symbol of a person slipping over ?.
I always think it means 'This Way To The Fish Counter'
