I’m a great believer in celebrating good examples of communication wherever you find it. So I’d like to apologise to my fellow rail passengers on the 14.58 train from Peterborough to Norwich last Sunday afternoon for hanging around the train WC with my camera phone.

Fear not dear reader, there are no prurient revelations to be confessed here; my motives were driven purely by professional interest as a communicator.

Lifting the lid in the said WC – in itself a hygienically challenging feat – I came across this great message which made me chuckle.

So why is it a piece of great communication? I think there are two reasons:

• Well targeted – can’t argue with its relevance for everyone who uses the WC
• Amusing – it has a serious message well balanced with a bit of humour. It can be hard to get the tone right when you want to introduce a touch of levity, but I reckon this gets it just right.

Not bad for toilet humour…
