Having the free run of a bookstore might be the stuff of some people's dreams, but for one tourist in London it turned into something of a nightmare.
David Willis, from Dallas, Texas, was accidentally locked inside a Waterstones store in Trafalgar Square, London, on Thursday evening. Waterstones is Britain's largest bookstore chain by sales, according to industry research firm IBISWorld, with 37 percent of the market share. It has close to 300 stores across the country.
Willis sent his first tweet about his predicament – along with an Instagram image of closed shutters – at 10.11 p.m., claiming he had been upstairs in the store for "15 minutes" and "came down to all the lights out and door locked".
