If you went to a food restaurant and the person serving the food had some kind of racist symbolic feature what

would you do? I went to a hot dog place today, and I have been going every other day. But today was crazy. The lady had a confederate flag apron. I should of have known something was up the first time I went. But I try not to judge a book by it's cover. I live up north so it is rare you see this. The place serve great food too. Do some people wear the flag for a fashion statement or ignorance?
