Here is the perfect sign. Without being rude it says exactly what needs to be said. The problem is that polite signs usually get ingnored so expect the Fox to be replaced with a four letter word beginning with ‘F.’
Mind you in this instance I think that the ‘Fox’ on the sign could be the bushy tailed variety, still mark my words when the sign is ignored the ‘F’ word will appear.
signs, Fword, ‘F’ Word, For Fox sake
