Both.  And I must be missing something because I don't think you remotely justified drink driving/drivers!

I agree that the hospitality industry does have a big responsibility - it does seemm on occasion to treat drinkers as a cash cow to be milked as much as possible.  But individuals need to have a culture shift too into understanding that being out of control is usually at least anti-social.  There was a recent poll which I can't find at the moment that said that many people - in the millions - went out in order to get drunk.  With that attitude, they will tend to succeed whatever measures the industry tries to put in place to monitor and stop them doing so.
