I think that people just don't like paying parking tickets, especially if they paid the meter (as several claimed). I think there is a big difference between "spending" money and "wasting" money. If people buy a nice shiny car, they did it because they enjoy the car. To them, it is worth the money they paid. However, a parking ticket is "money down the drain." They didn't receive any value for paying that ticket (no entertainment, no physical thingamabob, etc). I can get angry when accused of being in the wrong when I know I didn't do anything incorrectly, so I completely relate to those people who were told the meter expired and they knew they had paid it.
