My derision is reserved for those in power who don't seem to care about the rest of us. Sadly human history is littered with innocent billions. I would gladly support anyone who can help them.
I imagine thats due to estimated probability on your contracting virus in shops compared to sitting inside a restaurant. The current belief is thatmost individuals need to be exposed to a contagious person for over fifteen minutes to contract CV19. Speaking for myself, I rarely spend that long with someone in the newsagent or Tesco's!
