Although it is no longer customary to offer visitors a straw through which to drink from a communal vat of beer, today tea or coffee may be offered from a shared pot, or a glass of wine or spirits from a shared bottle. And when drinking alcohol in a social setting, the clinking of glasses symbolically reunites the glasses into a single vessel of shared liquid. These are traditions with very ancient origins.
