Me and my wife attended Costa Coffee in Llantrisant (by the hospital). Upon arriving a member of staff told my wife and I where we could stand whilst queuing, instruction which we followed. When we arrived at the counter Sophie (duty manager) told us we couldn't stand together. We explained to her that I had hearing difficulties (suffering from tinnitus) hence I was with my wife. We both are mask exempt. She then said I had to wear a badge, however this is not a legal requirement, clearly she did not understand the government's guidelines. Poorly trained, rude and clearly felt that humiliating customers was the best course of action to take. She then continued to humiliated us by saying that we should have told her earlier that we had problems and refused to serve us and refused to talk. I tried to explain, however she walked away saying that we would not be served in that store. None of the staff were working from customers or one one another at 2m, which is a requirement. In fact it when learning the site we had to walk within 2m of both sitting customers and those standing in the doorway. I managed to get her name from a member of staff who was clearly embarrassed by their manager's handling of the situation. I am trying to make a formal complaint however Costa does not seem to care, especially looking at the reviews found all over social media and the internet in general. I feel that she was attacking my disability, this is unacceptable and humiliating me because I needed my wife to be able to hear her clearly. I will be seeking legal advice.
