Taunted at Starbucks

My mother and I are Korean Americans, we were traveling in Florida for business so we stopped in a Starbucks and while we were waiting for our order a group of 4 people at a table started staring at us with very disgusted looks, two of them pulled up their shirts to cover their mouths. They as a group then proceeded to point, laugh and taunt my mother and I, they even mentioned the “coronavirus is here.” My mother and I are not confrontational people so we stood there and avoided eye contact until our drink was served and immediately left. I was left shocked and somehow felt disgusted with myself because I was viewed as inferior simply based on my looks. I sometimes get anxiety before going out for that reason.
