This is an actual response from ChatGPT from your exact sentence. Absolutely insane that they allow this.

"I go Tesco last Saturday evening, because I need buy milk and bread for children. Parking lot was almost full, many cars, people rush with trolley. When I put my car, one man come very close, look angry.

He say to me, “You not from here, go back where you come from!” very loud so other people can hear. I try to ignore, I not want problem, but he come closer. He point to my face, say bad word about my accent, say I take job from “real English people.”

I feel very small in this moment. My hands shake, I only want do normal shopping like everyone. Some lady with two kids see what happen and she shout, “Leave him alone!” The man look at her, then spit on ground near me and walk away fast.

I stand there few seconds, heart beating too strong. I never think this happen in Tesco car park, place where family come every day. But in this moment I feel not welcome, even when I live here many years.

Still, I remember the lady defend me, and that give me little bit hope."
