"Kiss, Bow, Or Shake Hands" - that is, indeed, the question.
The answer, naturally, is that it depends. Not particularly helpful (unless, that is, you are of the delusion that your way is the only way - but I'm guessing not since you found this book).
While I'm sure the book could benefit from being updated a bit for the 2020s, this is a fantastic starting point if you're (cluelessly?) operating in an international business space. It covers some basics, some nitty-gritties, and some proper manners - situationally speaking, of course.
Handy, very handy - or, so I guess, I haven't really had to use it much in a professional capacity. However, it's also super interesting if you're just curious, so I definitely think it's worth picking up should you stumble on it (and that's a real possibility, btw it is a bit brick-y).
