Interesting link embs, and it says 7 million (idiots) attend A&E per year when drunk. 

I also feel sorry for the paramedics - I saw a documentary once about them out and about on weekend nights and they get subjected to abuse while trying to help stupid drunks who take no responsibility for themselves.  Charging them might make a proportion of them think twice if they have any functioning brain cells.  Difficult in the odd case where someone might have had their drinks spiked I suppose, but I imagine that would be a small proportion judging by some morons around where I live who get caned on a regular basis, start fights and fall in the road.
