"Awful experience"

I went yesterday to the Urgent care section with my brother. We arrived 6:45pm and we knew that last patient acceptance is at 7pm while the unit closes at 8pm. We have been told from a rather irritated receptionist that we cannot be accepted and we should go tomorrow. For her own good luck i didn't keep her name in order to mention that here. When I asked for the reason she said that they were very busy and they were turning down visitors from 6pm, btw in the waiting room only 2 people were waiting to be seen! I asked her: do you call this busy? She didn't have a straight answer by telling us that "we reserve the right to turn down people when we are busy!" I asked her do you have only one doctor available? She said "yes". Now you reviewers tell me please if this is a unit with dignity for urgent care patients! One of the most famous hospitals in London having 1 doctor in urgent care treatment and at least 2 people behind the reception. This is how your taxes are utilized in NHS! Worst health system on earth! Feel free to go and waste your time! Ridiculous!
