And don't let friends, family and guests drive drunk!
We have the key basket, that is overseen by one of the tea teetotalers in the family. Keys go in when you arrive at a party here, and don't come out again unless the totally sober keeper of the basket feels you are sober. If you don't get your keys back you get a ride home from someone who IS sober, I'll call ( and pay for) a taxi, or give you a blanket and pillow and a corner to sleep it off in.
Just like barkeeps are now being held responsible if they continue to serve patrons who have had too much, the hosts and hostesses should be careful of their guests!
