Then there is the matter of staff. After the collapse of Zimbabwe under Robert Mugabe, the Johannesburg restaurant sector was overrun by legal and illegal migrants. Zimbabwean waiters and cooks essentially keep their country afloat by sending part of their earnings to relatives back home. In my experience, they are never satisfied with their tips. Afrikaners also prefer being served in Afrikaans, a language at least understood by most local blacks. Zimbabweans consider Afrikaans an irritation, and sometimes make it arrogantly clear that they do not speak it. There have also been rumors of Spur waitresses dripping body fluids into the food they serve to whites.
A prejudice is a preconceived belief, opinion, or judgment toward a group of people or a single person because of race , social class, gender , ethnicity , sexual orientation , age , disability , political beliefs, religion, line of work or other personal characteristics. It also means a priori beliefs (without knowledge of the facts) and includes "any unreasonable attitude that is unusually resistant to rational influence."  Although positive and negative prejudice both exist, when used negatively, "prejudice" implies fear and antipathy toward such a group or person.
