"very rude nurse"

I went for a blood test today with a referral from ENT specialist. No one was in the waiting room and the nurse standing at the back talking and laughing. When I asked one of them that came up to the desk, in a very arrogant way told to stand in a queue where there was no and wait. Once you have called me to study, without disinfecting hands and gloves took up for blood donation. I can not imagine how you can approach so irresponsibly to his work and patients.
