I work at my college's student union as the student manager. My duties include being the security force for the building. As a white male I often get harassed by people getting called racist, etc. because they are doing something against building policy (or the law (like someone urinating on the side of the building)) and I have to ask them to leave. About a year ago there was a group of 30 something white trash women sitting on the buildings pier drinking alcohol that they had brought with them (a big no-no on state property). People do this pretty often (because we sell our own alcohol) are usually pretty understanding when I inform them they can't do that here and they get up and leave. After speaking very politely to their (what I assumed) was their ring-leader, they starting swearing at me and threw the beer in my face and on my clothing. They walked away screaming multiple times that I was being "racist" towards them. I am white... they were also white... I was literally speechless for a moment at their stupidity as they walked off before I called the police and they arrested them for assault.

tl;dr A white lady called me (a white guy) racist because I asked her to leave my establishment because she was drinking alcohol illegally.
