they have a responsibilty to an extent maybe not in that case, but say they are far to drunk and actually colapsing then they should make sure they are safe. but at risking your licence? i would probably just through them out too. i mean if you phoned the police to take them home you'd get busted for serving them drink in another instance at my old work, one of our security staff got taking in by the police for one night cause there had been a fight and they left one of the guys to wonder off when he was bleeding. normally we did take them in and clean them up, make sure they didnt need hospital treatment. all the other clubs would just throw the away. even if it was like a bottle smashed over their head
