I think you should have 2 clerks registering pts that need lab services and 2 clerks that need x-ray services. I had to wait for over an hour to register and get blood work on my last visit where was a gentleman that had been waiting for 1 1/2 hrs. to get blood work that way the waiting time is (unreadable) this long. 22-Mar-2017 Appointment was for 11:00 am, was walking out at 11:08. Handwashing - could answer because it wasn't observed.
