Imagine it's your birthday and you couldn't book a table at your favourite high-end restaurant. Suddenly, while you were talking to your friends, your phone buzzes. It's not another birthday wish but it's the Dyne app. It tells you that someone has cancelled their table at Hakkasan Mayfair tonight and it's exactly the place you wanted to celebrate your birthday. You immediately open the app and reserve the table for you and your friends.
