Something happened on the way to the plane

Last night, at the Mumbai airport, I gave my boarding pass to the person at the counter and got into the shuttle. The shuttle travelled for about a hundred meters, made a U-turn and returned to the same spot we started from, but on the opposite side, and we got down and got into the plane, which had been waiting for us morons patiently all the while, right outside the building, probably shaking its head at the foolishness of it all.
