I really don’t think many people are afraid to go into public settings. Maybe not into a crowd, sure, but a restaurant? The holdup there is from the government, not the public.
With that said, this is going to vary by region. There is absolutely a large percentage of people wanting and willing to go eat indoors at restaurants right now, I just don't think that number represents a majority.
