Bloody Immigrants

A Zimbabwean arrives in Johannesburg as a new immigrant to South Africa.
He stops the first person he sees walking down the street and says, "Thank you Sir for letting me in this country , giving me housing, food, free medical care, and  free education!" The passerby says, "You are mistaken, I am Nigerian." The man goes on and encounters another passerby. " Thank you for having such a beautiful country here in South Africa!" The person says, "I not South African, I am from Mozambique."
The new arrival walks further, and the next person he sees he stops, shakes his hand and says, "Thank you for the wonderful country!" That person puts up his hand and says, "I am from Middle East , I am not South Africa!"
He finally sees a nice lady and asks, "Are you a South African?" She says , "No, I am from Kenia!" puzzled, he asks her, "Where are all the South Africans?"
The African lady checks her watch and says..."Probably at work!!
