This is not someone who had one bad night - this was a long term functional alcoholic whose progression brought him to the point of trying to balance his blood alcohol level somewhere between obviously drunk and serious withdrawal - hence the bottle of vodka. It may seem strange ( and it is clearly illegal and wrong) but he would probably have been in better shape once he had had a chance to take a couple of belts from that bottle. I hope he moves on and accepts the help that is available and 3-5 years from now can say that this day saved his life.
