And ask for Carl I think his name is, the black guy with the very friendly manner. He not only didn't hurt at all but treated me as if I was the only person he had seen that day, with plenty of eye contact (not scarily so) and asking about me in a truly friendly manner. His colleague, middle aged black woman, was so rude and took a personal call on her mobile without apology before she had finished with me! And it hurt and she said "Of course it hurts, I just put a needle in you!" Definitely avoid early morning and as above, I went about 11 and waited 5 mins.
