Fast food chain Lotteria has announced it will hand your money back if you don't like their new burger set. You'll get your 360 yen back provided you haven't scoffed down more than half so it's not quite a free lunch. You'll also be asked to fill out a questionnaire saying why you didn't like the burger before you are reacquainted with your money. The offer stands until the end of July and is available Lotteria restaurants nationwide.
