drinking from the public jug

The Lebanese have this way of drinking that is quite distinctive. When you are in a restaurant there is a jug of water on the table. In most places it is a jug not different from one you see in any museum, or you see in fragments in an archeology site - made of plain reddish-brown clay. The more modern places have glass jugs with the name of the place on it. The Lebanese just drink from these jugs. Everyone at the table just passes around this jug and just drinks. They all drink such that the jug never touches their lips, and the water just pours out of the jugs in to their mouths. It is funny looking around a restaraunt and watching everyone doing this. It is like watching men women and children pass around a quart-carton of milk and drink from it, something Americans would never do in public.
