Can I ask him to sign my book first incase I gett hrown out?

Yes,good idea.As your saying Goodbye do it. And then if he gets funny about it just say its totally natural and a common way to say goodbye in the part of england your from and nobody cares where your from. And if your feeling daring you could go further than the grope of the buttocks and use the same excuse although I don't think that would be easy.
