I wholeheartedly agree with the previous, previous reviewer. This book is both witless and offensive.
One particular 'suggestion' advises readers to 'ask for sandwich fillings whilst pointing at others'. A little thought on behalf of the book's publishers would have caused them to realise that people taking this 'advice' would result in many, many lost man-minutes over the course of countless lunchtimes.
Not to mention the annoyance caused to the UK's sandwich making sector, already an under appreciated and oft abused (both verbally and physically) community.
Why 'Leila Johnston' (if that is indeed her name) would want to cause worry and inconvenience to people I have no idea.
Mind you, I did like the suggestion about pretending to be a robot.
