I am not doing that many appointments -- much of my work is drop-off and mail-in -- but I share your concerns and my kids (ages 37 and 38) are telling me to tell my OCD clients to go away and come back this summer.  They are concerned about my health; I am concerned about my office assistant, who like me is in the over-60 "high risk" group.  She deals with six to eight visitors a day, including the FedEx delivery person who uses one of those hand-held devices requiring a signature with a finger.  If she asked me to shut down, I would.  

Two weeks ago this was a "hoax."  Today, many of us realize that everyone will get sick and 1% will die -- including younger victims.  Containment is not going to prevent any infections or deaths, it is just going to spread them out so not everyone goes to the doctor or hospital at the same time.  

I won't be surprised if Block and the other mass preparers (not that Mass is being offered in many places right now) announce in the next few days that they are closing down.  I think they must be exerting pressure on IRS to announce a blanket extension to June 15, and that will be forthcoming in the same haphazard way that everything else has been conducted.  

Meanwhile, you are between a deadly virus and a hard place.  If you can find a better job, do it.  If you can't, we can still pray for you at home.  Consider "worked for a jerk" for your headstone.
