Sorry, I have a hard time believing that there is an actual shortage of O2 in Washington state. Medical O2 demand hasn't changed much, ABO O2 demand is dictated by Boeing and they haven't been using very much for over a year, and Technical O2 (which comes out of the same container as Medical O2) demand can't be very high with all the stay at home orders. The only thing left is the truck driver that either picks up or delivers may decide that walking into a dive store to deliver 2-3 bottles just isn't worth the risk.
