If you are MO or lean more towards modern ivrit, you’ve probably had the experience of going to a simcha at a DEEEP Litvishe shul and going up to someone after davening and offering a crisp “shabbat shalom” only to be met with a quizzical or hostile stare (sort of like someone who goes around deliberately running chalk on a blackboard). By the second or third time, you quickly find yourself doing your best “gooooten shabboss” followed by a request for directions to the kiddush.
