Blind pilot?

The flight was from San Francisco to Los Angeles. By the time the plane took off, there had been a 45-minute delay and everybody on board was upset. Then unexpectedly, the plane stopped in Sacramento on the way. The flight attendant explained that there would be another 45-minute delay, and if anyone wanted to get off the aircraft, they would reboard in 30 minutes.
Everybody got off the plane except one gentleman who was blind. His seeing-eye dog lay quietly underneath the seats in front of him throughout the entire flight. He had flown this very flight before and the pilot approached him and, calling him by name, said, "Lou, we're in Sacramento for almost an hour. Would you like to get off and stretch your legs?"
Lou replied, "No thanks, but could you please take my dog out to go potty?"
The pilot replied "Sure Thing!"
The pilot then walk off the plane with the seeing-eye dog, who promptly lifted his leg on the plane's landing gear.
But the real problem was that pilot was even wearing sunglasses and walking with what was obviously a seeing-eye dog. People scattered. They not only tried to change planes, they tried to change airlines!
