Yup! I used to hear all the time about how the heavy drinking that takes place between men at business dinners, is done to gain "trust" and "good will" between people who are trying to form a business relationship.

In response, I used to tell my students that while many Americans drink lots of alcohol, we actually discourage too much of it (or any) during business dinners/lunches, etc.

I explain that in the U.S., if for example, you are seeking my investment in your business venture, and you drink too much (more than two drinks), then I will likely think that if you cannot control your drinking, then why should I entrust my money to you? (Students always write these things down -- rather amusing).

I simply try to give them a different perspective about business-related drinking.

Unfortuantely, I didn't see much refrain from heavy drinking from my university-age males, but many of them did not smoke, so some progress is bring made there.

Smoking and drinking seemed to be a largely male endeavor in China, but in Korea, it is equal among genders (by my observation).
