~ Der Stammtisch ist der Tisch ~
We are creatures of habit and groups that gather for a friendly drink at a tavern usually sit at a particular table. The glass stein with a transfer scene is ca. post WW II.
Der Stammtisch ist der Tisch, in dem die Leute sitzen, die immer dort sitzen. Prost!	The "Regular's Table" is the table, at which people sit, that always sit there. Cheers!
