She called the cabin crew attendant over to complain about her seating. "What seems to be the problem, Madam?" Asked the attendant. "Can't you see?" She said, "You've sat me next to a black. I can't possibly sit next to this dirty disgusting human. Find me another seat!" "Please calm down, Madam," the attendant 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." A few minutes later, the attendant returned with the good news, which she delivered to the lady, who cannot help but look at the people around her with a smug and self-satisfied grin. "Madam, unfortunately, as I guessed, 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 attendant continued. "It's most extraordinary to make this kind of upgrade, however, and I have had to get special permission from the captain. But, according to this _ , the captain felt that it was unbelievable that someone should be forced to sit next to such an obnoxious person." Having said that, the attendant 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."
