Scrimping

Other threw down the gauntlet yesterday. After I announced that I had virtuously taken the SuperShuttle to and from the airport in San Francisco at $20 a pop (including tip), saving $40 each way from what it would have cost to take a taxi (about $60, including tip), Other decided to take the plane to the train on his return from Florida for $7.50, saving $52.50. Wow! I don't know if I can beat that, except by walking.
