CVS review: Covid test - rude technician

My dad was scheduled for a covid test; however, I entered the wrong year digit of his DOB. This was our fault; however, it does not take much to change the DOB. When he showed up at the CSV 15421 Brookhurst St, Westminster, CA, the pharmacist technician that issued the test was extremely rude to him. Her name is Bieu. First, Bieu speaks Vietnamese, which is my father's language. She raised her voice and gave him such a hard time for not speaking English, not to mention my dad is 79 years old and has Alzheimer's. So please train your representative to represent CVS to be kind to the senior, especially if they are there for a reason. Please find another career if you can't be kind (when it's your job as a healthcare provider). Not to mention this is your people, and treat the senior with respect, please.
