"Poor customer care during my retinal screening"

Arrived at Barrhead Health and Care Centre for Retinal Screening yesterday afternoon. Receptionist barely looked up from her computer to take my name and tell me to take a seat. A man arrived at the doors and said something inaudible. I knew he hadn't said my name so I didn't get up. He said 'eye screening' (I think!). I apologised and explained I hadn't heard my name as I had expected. He looked at me as if I was from another planet and made no response. I followed him down empty corridors to a room where he pointed to a chair. Instructions and 2 questions were barked at me very quickly. No drops were put in my eyes. He mumbled something about results which I didn't catch and expected me to get up to go when he hadn't switched the light on and I couldn't see properly as well after the equipment flashes. I was left to find my way out along the corridors. I have not felt so intimidated or come across such rude customer service in years.
