What message would be sent out? Just drink as much as you like , get paralytic . You'll be alright because you will be looked after and treated with kid gloves .
Hose them down , leave them to stew in their vomit and charge them with being drunk and disorderly!!
Drunks need to take responsibility for their own stupidity .
If this service goes ahead as no doubt it will in this soft country then charge the drunks for the treatment they have received.
