Waste of Time.
I went for a covid test in preparation for a day case operation. I thought the person doing the test quite unpleasant and unnecessarily rough. When I went for my hospital appointment a few days later, I was told that the tests hadn't been sent off for testing and all of us waiting for operations that day were sent home. All of the hospital staff, doctors,nurses and anyone else connected with those operations were all left with nothing to do, what a disgraceful state of affairs.
