Do South Africa's whites whine too much and are blacks too humble to grumble?

SHOOT: Here's some background. An old white women caused a fuss in a bank where she stood for hours. Everyone else in the bank was black. She left the bank with her hard-won document, kicking and screaming, while her black audience had just queued quietly and said nothing...

SOWETAN: The people in the bank then started talking among themselves about Jane but not about the pathetic service they were receiving.
No one called the manager or questioned why the queue was moving at a snail’s pace.
All the people in the bank were black and Jane had been the only white . Do we accept bad service just because we are black? Is it because black people are inherently patient?
I don’t have the answers.
But I know that no human being wants to stand in a queue for three hours, unless they are voting a government into power.
Poor service is poor service. It has nothing to do with race, class and age.

SHOOT: Good point. We're patient to stand in queues to vote a government into power. So are whites whiners and blacks too humble to grumbel? Perhaps a little of both. Undoubtedly complaints from both sides are due to rise based on this:

She looked as if she was in her late 80s and was accompanied by her domestic worker of 16 years. Jane told interested onlookers that the mother of her helper had worked for her for 36 years before transferring her duties to her daughter. Finally Jane got her piece of paper – but it was the wrong one. She shouted again: “What’s wrong with you people? I wait for an hour for this paper and then you give me the wrong document!” The tellers and the bank manager were unmoved by her complaints . Jane moved from the enquiries counter to the tellers as she fumed in anger. She also complained about the length of the queue and then told us of a recent operation on her leg. She shouted again: “This is the worst bank in South Africa. No one backed her call.
