In this day and age, regardless of the virus, this is a very disrespectful way to conduct business if not just down right stupid.
If you do not have the time to communicate properly with your clients, you should not have any. Hell I was talking to clients yesterday and it was Christmas Eve.
Communication is key and unfortunately many folks who are in business have no idea how to do it. You may be good at what you do but if you cannot interface well with the folks writing you checks, they will soon stop issuing them.
And should!!
