I was flying from San Francisco to Los Angeles. By the time we took off, there had been a 45-minute delay and everybody on board was ticked. Unexpectedly, we stopped in Sacramento on the way. The flight attendant explained that there would be another 45-minute delay, and if we wanted to get off the aircraft, we would reboard in thirty minutes.Everybody got off the plane except one gentleman who was blind. I noticed him as I walked by and could tell he had flown before because his seeing eye dog lay quietly underneath the seats in front of him throughout the entire flight. I could also tell he had flown this very flight before because the pilot approached him and, calling him by name, said, “Keith, we’re in Sacramento for almost an hour. Would you like to get off and stretch your legs?”Keith replied, “No thanks, but maybe my dog would like to stretch his legs. Would you take him for me please?”Now picture this. All the people in the gate area came to a completely quiet standstill when they looked up and saw the pilot walk off the plane with a seeing eye dog! The pilot was even wearing sunglasses that day. People scattered not only trying to change planes but also trying to change airlines!
