No original source known, but supposedly a true story.

A airliner flying from Seattle to San Francisco unexpectedly landed in Sacramento because of a minor problem. The flight attendant explained that there would be a delay and if the passengers wanted to get off the aircraft, they could re-board in 50 minutes.

All passengers deplaned except one gentleman who was blind. His seeing eye dog lay quietly underneath the seat in front of him. He had flown this flight before and the pilot approached him and said, “Keith, we'll be here for almost an hour. Would you like to get off and stretch your legs?”

The blind man replied, “No thanks, but maybe my dog would like to stretch his legs.”

Picture this: All the people in the gate area came to a complete standstill when they looked up and saw the pilot walk off the plane with a seeing-eye dog and even wearing dark sunglasses.

They scattered… and not only tried to change planes, but change airlines as well!

Morale to the story:
Things are not always as they seem!
