T.J. Maxx

I was a traveller and I went to TJ Maxx on 01/13/2019. I was looking at some bags there and a young black lady came and asked me, "did you find anything good?". I said no, I'm just looking. She told me not to take anything out of the store and said she was joking.

I felt so offended, but I went blank and said nothing to her. After leaving the store, I felt that I should say it's not funny at all but I didn't.

I didn't know if she was unintentional to say that word or she considered me as a furtive one to take sth out of the store, or I was an Asian?

Actually when I was in UK, TKmaxx was my favorite stores there. But now I will never ever visit TJmaxx at all because of an "unintentional " word.
