"That's probably what an Oriental man like you do?"

I was waiting outside a mexican restaurant for my friend to pick up his order. A old white male comes up to me and asks me this question, "Oh man, what would you do if you broke a finger? Like, use your feet? That's probably what an Oriental like you would do.?"

After this, the male looked away in hatred and walked into the restaurant. I personally was perplexed at the immense stupidity of the question the old white man had just asked. Entitlement is something I see as the problem here.
