Not so long ago, after twelve hours in the air, I found myself stranded at an international airport at 2 in the morning. The flight had been delayed—my pre-arranged pickup had abandoned his mission or just not shown up, and there was one taxi about to pull out and head home for the night. I was still 90 miles from my room for the night, and offered him twice the normal rate to take on one last fare, which he pointed out, wasn’t even close, direction-wise, to his own waiting bed. But for twice the money, and for Allah, he would do it.
