lines of accepting responsiblility for someone else question (drunk driving)

i work in a large corporate restaurant (applebees) and they are extremely careful when it comes to liabilities. that being said, we are told that ultimately the consumer is responsible for knowing their limits and if they wreck their car after they leave, tough shit for them. we are however, encouraged to do our best to prevent that from happening.

cliffs: legally you would not have been responsible or accountable
