A VirginTrains passenger identified only as “Adam” discovered too late that the lavatory stall he had selected was out of toilet paper.     

But like many people, Adam takes his smartphone with him everywhere. Desperately, or perhaps ingeniously, he Tweeted to @VirginTrains his location and predicament. “We’ll send someone down to you,” came the prompt reply, and very soon a gentleman “looking quite worried in a full black suit carrying (a) toilet roll” knocked on Adam’s door.
