Ohh, I have got a gem for you.
I was in charge of interviewing staff at a university, and I was the accessibility coordinator. My job was to come up with a plan on how to make the university more accessible for people with disabilities, and to provide training for staff so that they did not inadvertently discriminate against those with disabilities.
FYI (I am a non-white male) One day I was about to interview the art gallery coordinator at the university, and when I came to her gallery I saw her door. I was about to enter when a young girl (probably a summer student) told me that I could not enter, and to just go into a waiting room, and she would try to help me soon. I could see where the coordinator's office was, but this lady was preventing me from going. I waited 20 minutes, and it was obvious she forgot about me. So, I walked in to the room anyway, and the girl stopped me, and asked me if she could help me. I told her I had an interview, and she said she was not aware of any of her colleagues having an interview booked. Suddenly, the coordinator walked in, and said, “Hi James, I’ve been waiting for you for a while. Where have you been?” I saw the summer student start to blush and become suddenly quiet. I think that girl learned not to assume things about people before you have taken the time to know them. Later, I ended up training her, and all her staff on how to avoid discrimination, and how to show respect to all people they dealt with. Did I mention that one of those being trained by me about discrimination, was the girl who had given me a dose of discrimination herself.
