It would be all too easy to mock the tourist who walked off a pier because she was too busy checking her phone to realise she'd reached the end of the walkway.
But haven't we all nearly been there now? If it isn't a pier, it's a busy road or a tree or a lamppost or an angry commuter or a confused dog or a bin or a glass door. Honestly, real life doesn't half get in the way of technology sometimes.
You'd be forgiven for walking off a pier while checking blips - they're very diverting.
