Entitlement

I was to have an asses at Midstream Eyecare, it seems I was scheduled for 14h15. I had called the day before to confirm my appointment and I thought that my appointment was at 14h30, so I arrived at the practice at 14h25. The optometrist was busy with a student in the front area and I started the paper work. She then comes saying we are late and that we must go in quickly. I obliged. She then asks my name and I tell her it is Coceka, she responds 'Okay Thabeng.' Of course as was shocked and I repeated my name. She got offended by the fact that I corrected her and rudely told me that she is Afrikaans and cannot be expected to pronounce it correctly. This attitude of entitlement shocked me. She then went on to insist that I repeat her name after her. I found this patronizing, rude and absolutely unnecessary. This is unacceptable behavior and will not be tolerated. I am a healthcare practitioner myself and I would not interact with a client in this manner. It goes against the norms of health service and should be condemned!
