"Oriental like the rug"

I was eating lunch at a hotel when I hear behind me, “You need to go back to your country, you’re carrying a disease.” I thought I misheard, I turned around and said excuse me. She repeated it. I was so shook it took me 5 min before I picked up the phone and recorded. Then she had the audacity to walk over and record me. She acted like it was really cute what happened, even denied and minimized what she said. I asked her again “I should go back to my country, right?” She says, “You should where they speak oriental perfectly... yeah, oriental like the rug” and laughed.
