Oy vey that we should have sha’alos like these!
This sha’alah will only make sense if everybody else says Gut Shabbos. Unfortunately, in some places – especially Brooklyn – if I dare try to say Gut Shabbos to anybody – usually 2 things will happen – either he or she will walk right by ignoring you or stare at you as if you came from outer=space. When people start saying Gut Shabbos one to another then we could worry about this partcular Sha’lah. By the way, Shabbos is in a few days – so to everyone – Have a Gut Shabbos!
