There's the story of pilot who, walking through the cabin during a flight from Karachi to Paris, noticed a blind passenger with his guide dog. Being an animal lover, he asked the man if he would like him to take the dog for little walk along the runway when they landed in Athens. The offer was gladly accepted.
A new batch of passanger was about to board the aircraft. Seeing the pilot with the guide dog, they stopped dead in their tracks, dismay on their faces, then turned and went back to the terminal building to ask if they could change their tickets for another air line.
