I have four I know by name. EMS gets called, they bring them in to the nearest hospital which happens to be us. We put em in a gurney and tell them to sleep it off until morning. One usually gets a loading dose of Dilantin too because otherwise he will have seizures. If the others start to get the shakes, they get a mg of Ativan PO, then back to sleep until the morning when they are offered the services of the social worker.
The only shelter is in downtown LA, which we KNOW they aren't going to go to. They end up walking out and come back within a few nights for another bed and breakfast treat.
