BioLife Plasma Services review: Customer service and mask policy

BioLife employee (manager) Adam Foster was rude and has bad costumer service. Especially when we are here to save life's. I expect to be treated fairly.
I entered wearing a proper face covering. The employee told me I had to put on another mask I can't wear cloth mask he stated. Wearing a cloth mask himself not FDA approved. My mask is FDA approved. Also I've been donating here since Jan 4 and wear this mask every visit. It was not a problem for any other employee including the nurses. He singled me out as if I didn't have one at all and wouldn't allow me to continue the process unless I had on 2 mask. Idk if I was racially targeted but it kinda feels that way when I see other ppl of different ethnicity with cloth mask on and not double mask like my self. I told another employee witch intern ask him about the situation and he told me well he's a manager. I felt I needed to report this after seeing others with the same type of mask I had on and not wearing two mask. I have pictures aswell.
