Umm, well, I'll be heard, b/c I get yelled at by librarians at libraries when I'm in my normal speaking voice...
But 5 friends together, now 30 ft apart (since they all have to be 6 ft apart)...gonna be some LOUD talkers needed to hear each other...and if you get 10 of you...heck, you might not fit in the same place.
Social distance at 6ft works for 2 "family" groups to interact, but you start getting 5-6 single different households together...and well, it's not gonna stay long...
