I once heard that we are not suppose to greet each other with "Good Shabbos" once we have davened Mincha on Shabbat afternoon, possibly having to do with the death of Moshe/David/Yosef at that time.
I find myself in an uncomfortable position when responding to people greeting me with "Good Shabbos" after I have davened Mincha. This is especially problematic for people who might daven an early Mincha.
A few questions: 1) Is there a source for this? 2) How should I greet people I see after mincha on Shabbas afternoon? Is it better to avoid saying "Good Shabbos"? 3) How should I respond when someone greets me with a "Good Shabbos" after I have davened Mincha? Thanks!
A. Horav Shlomo Miller Shlit’a maintains that we are not to be concerned with the above, and you can always greet Good Shabbos.
