BioLife Plasma Services review: donating blood plasma

Date: 5/08/2019, Time: 6:15 am - 6:40 am approximately, Employee(s) involved: Tammy, Kim, Dawn and Supervisor who I can point out.
After all my levels were checked and approved I had to dookie. When I came out of the bathroom Kim stated that they were waiting for me. Dawn was the only other employee standing beside her at this time. I rubbed my stomach in relief and stated with a smile that "I'm sorry, my stomach was killing me this morning. Had to get that out of me. I'm good now". Mind you I dookie almost every morning and had just ate a sausage egg and cheese biscuit from Kwik Star. I proceeded to my designated area to begin donating. Once I sat down, Tammy came over and said she needed to see me for a min. We went into a office where she told me I couldn't donate. I asked for a site manager and she went and got the supervisor whose name I didn't catch but face I can point out in a line up. Before entering the room I heard Tammy say and I quote, "...just tell his black [censored] he can't donate today and send him on his way". That's when Tammy and the supervisor entered the room. I pleaded my case to which Tammy was the only one responding. I asked how to file a formal grievance to which Tammy stated that she didn't know and to figure it out myself. This to me is unprofessional. Also discrimination and a violation of my declaratory right to equal opportunity as well as my right to pursue happiness. The only remedy for such action is monetary and declaratory relief.
