1. No. Introduce the more important person first. You should address your client and say "Mr. Beta, I'd like you to meet our Vice President of Development, Ms. Alpha." (Alternative answer?introduce the client as the more important person!)
2. No. In Japan (unlike in the United States or the UK), business cards are taken as a serious reflection of their owner and are exchanged with great ceremony. Researching the importance of business cards in various cultures can help in avoiding embarrassing faux pas.
3. Yes. When your client steps out of the car, (s)he will be on the curbside and therefore won't have to deal with getting out in traffic or sliding across the seat.
4. Yes
5. No. If you do, then you're toasting yourself.
6. B. It's not a cup of coffee, for heaven's sake. And don't slurp, either.
7. D. It's more polite not to call attention to the fact that you can't drink champagne.
8. D. Leave it on your chair. Definitely don't put it on the table--what if you have crumbs on it?
9. B and C. Sort of a trick question, but this is important.
10. A, B, or C. It's terribly impolite to arrive early.
11. A, B, C, D, and E. In other words, it's rarely improper to shake someone's hand. Make sure you have a firm (but not painful) handshake for both men and women.
12. B. Make eye contact with all of the individuals you're talking with.
13. No. Again, don't call attention to your dislike of your host's chosen beverage.
14. B. Indicating where your guest should sit will make her feel more comfortable.
15. B, C, or D. Just don't grab it first unless you're playing one of these roles.
16. A. You've waited 30 minutes. Expect an apology later, though.
17. D. Call and set up another appointment. And don't forget to apologize for your error. Imagine how you'd feel if it was you!
