I think enough people will figure out how to "game" the system and have no problem doing it. It's always really just a few that make it hard for everyone, but those few are ever present unfortunately. It's so much easier to just charge a few bucks. Works just like a co-pay in terms of dissuading people from scheduling worthless appointments, but the money isn't enough to stop people who really need to see a doctor from being seen. As soon as they started actually charging for missed court reservations at the University courts, the problem vanished overnight. They do however allow cancelations up to 24 hours in advance without a charge. People know this, so enough people call in during peak hours in the winter and take the courts that have been cancelled. It works well.
