Fresenius's Heart of Lubbock Dialysis center of Lubbock is unprofessional. I wanted to check the jug of a sealed (protected for my own security) unit which was going into my body and the nurse technician (Ponji) chose to become insulted and took my actions personally as if I was blaming her for sabotage. The nurse manager (Stephanie) instead of pulling the nurse aside to guide her into not taking my desire to inspect the secured bottle personally and telling her that is my right as a patient decided to push me out of the place because "we cannot assist you here at this location." And to continue, "You need to find another place to do dialysis," and suggesting two places.
