William (Bill) Hill sends this memory -
When I worked as a Station Attendant in YYZ there was one gate where arriving aircraft were required to shut down their engines and be towed into the gate due to safety concerns for employees working at gates opposite. I was on the bridge and when I opened the aircraft door the Captain was there to greet the passengers.
One elderly passenger commented to the Captain. "Boy, I'm sure glad that you didn't run out of gas while we were in the air".
