At the heritage railway not far from where I live, the toilet facilities at the main station, while more than adequate during most of the hours when the station is open to the public, are apt to be insufficient on ‘event days’ rendering additional provisions necessary. One member of the management team has his own particular brand of humour, hence the sign in the photograph.
(I have also heard references to ‘spare gentlemen’ although I’ve never seen a corresponding sign.)
This post is part of my continued involvement with the Alphabet Photo Challenge.
