It may be the 60s taken a few steps further, but there are licensing laws and so-called responsible adults who should be supervising and controlling what goes on inside and outside places of entertainment. It was always my understanding that it was against the law to be drunk in the street and probably against licensing regulations to serve clearly drunk people with more drink.
The authorities are doing OUR kids no favours.
If (in this country) they want to stop the abuse of A & E departments, the early onset of liver disease, the spread of STDs, and cut down on working days lost due to this madness, then ENFORCE the law !
