Has anyone ever accused you of being racist?

Lmao yes. One time I was working at my job... And this couple walks in and I had to tell them to please put on a mask and I'm doing my job and as I'm going through the aisles I come back and they're not wearing their mask so I go up to them and I say can you guys please put on your mask and they do it and I walk away and then when they're ready to pay for their stuff they go out front and they complain and saying that I targeted them because they were black and I was a white racist girl and someone should talk to the manager about it that I called them out for not wearing a mask because I was racist and when I heard this I literally balled my eyes out and I was absolutely hurt and they were calling me the white girl in the green and I was just like what the fuck did they just say... Did they just assume what I was.. I am literally Native American Navajo they can go fuck themselves.
