Errrrrr....

Why do we need to have signs like this?

-Where have people been putting the nozzle?
-Have people been filling their car so that it overflows?
-Have they been stood there nozzle in hand, scratching their heads and thinking, "where did I get this from again?"

I could go on, but I really think we have signage overload now so no-one really bothers to read them anymore.
