Andreas commissioners say they had to have a sink unblocked in the village's public toilets at the weekend.
The local authority took to Facebook, saying someone had cleaned muddy footwear in the sink in the gent's loos.
They say that blocked the drain and meant a callout to clear up the mess.
On Facebook, the board's asking those responsible not to do it again.
