Perceptions. How People from other Countries deal with Ignorance

The other day Angie was getting food at a buffet.  The person serving looked like they were from another country.  The person serving bacon was trying to unclump some bacon that had stuck together.  The lady in front of Angie told the woman she could just serve the whole thing to her because she was going to tell her it was not enough.  The woman continued to separate the bacon.  She gave the woman two pieces of bacon.  The woman turns to Angie and goes "I guess she doesn't understand English!".  After the woman had left, the woman serving turned to Angie and says in perfect English, "Good Morning, would you like some extra bacon?"

That really irritates me when people do that.  I think that if my daughter was in the same situation, they would do the same thing to her just on her appearance.   She would either do the same thing or just cuss them out.  She could do just like the man on The Karate Kid remake, where the boy asks the man something in Chinese and he says that he is from Detroit.
