I don't feel that 'too much' is really specified here, it's more like 'a lot of' surely? (which isn't accepted)
Agreed. It's not a movie, loose translations aren't advisable unless we're doing idioms.
In Korea, people are expected to drink alcohol when in the company of others who are drinking. Refusing a drink from an older person is considered rude. It used to be the same with smoking (and still is to some extent now in China).
That might be the case but its better to be rude than causing an accident that might hurt or kill an innocent bystander by drinking too much or if you're a non drinker by drinking, or making a fool of yourself for generations to come. So go ahead and be rude if necessary. Let karma take care of it. NEVER LET SOCIAL PRESSURES DETERMINE WHO YOU ARE!
actually there are services there that even if they do drink after driving there, they can call someone and that person comes and gets their car and drives them home.
From a social perspective, Winston is correct. If you do not wish to drink you absolutely MUST say so before going so that they don't think you're a jerk.
Most business deals are actually done over drinks.
