On a BA flight from Johannesburg, a middle-aged, well-off white South African Lady has found herself sitting next to a black man. She called a stewardess (女乘务员) over to complain about her seating.

“What seems to be the problem, Madam?” asked the stewardess. “Can’t you see?” she said, “You’ve sat me next to a kafir（异教徒）. I can’t possibly sit next to this disgusting man. Find me another seat!” “Please calm down, Madam,” the stewardess replied. “The flight is very full today, but I’ll tell you what I’ll do — I’ll go and check to see if we have any seats available in club or first class.”

The woman cocked a snooty look at the black man beside her.

A few minutes later the stewardess returned with the good news, which she delivered to the lady, who could not help but look at the people around her with a smug and self-satisfied grin. “Madam, unfortunately, as I suspected, economy is full. I’ve spoken to the cabin services director, and club is also full. However, we do have one seat in first class.”

Before the lady had a chance to answer, the stewardess continued, “It is the most extraordinary to make this kind of upgrade, however, and I have had to get special permission from the captain. But, given the circumstances, the captain felt that it was outrageous（令人不能容忍的） that someone should be forced to sit next to such an obnoxious（讨厌的） person.” Having said that, the stewardess turned to the black man sitting next to the lady, and said, “So if you’d like to get your things, sir, I have your seat ready for you.”

At that point, the surrounding passengers stood up and gave an ovation（喝彩） while the black man walked up to the front of the plane.
