The trouble is, it's not just in pubs that parents can over indulge in drink. Drink is available almost twenty four hours a day (except on Sundays) and people can drink at home to their heart's content.
Clear messages about the health problems caused by drink are not getting through. Young people in particular are binge drinking to the point where they are admitted to hospital due to alcohol poisoning. It seems every night, drunken brawling is seen on our cities' streets. It's a sad sign of our society.
However, as you say Bounty, the answer is not to dictate to people how they should live their lives. the answer is to inform people of the dangers and allow them to decide for themselves what a sensible level of drinking is. Help is, and should always be, available to people who admit their drinking is out of control. People who are drunk and disorderly are, and should be, arrested for their own protection. Licensing hours have been relaxed far too much, however, it is still the individual who has to control their own behaviour.
If you know anybody who has drunk themselves to death (sadly, two friends lost long-term partners through alcholism) it is not a pretty sight. It is a nasty, painful death but nobody could stop those men from drinking, only themselves.
