"Go back to your f***cking restaurant"

Shopping at local grocery market, was in the aisle next to beers. White man talking loudly on phone comes to the middle of the aisle near where I'm standing and starts asking his buddy on the phone what kind of beer to get. I ask him to keep his distance given that he didn't have a mask. He turns to me, and says on his phone, "Hold on, I've got this oriental MFer bitching to me." I quickly leave the aisle, but the man follows me, yelling things like, "Hey Ching Chang Chong, go back to your f***ing restaurant and make me some chicken fried rice.”
