Undocumented Punch Card 'Features'

• If a reservation is paid with a punch, it removes the ability to edit the reservation
• If court time can be paid with punches, it won't scale up with the number of punches. 1 punch for 1 court is one punch for all courts
• If a ball machine is added to a reservation with a cost, the punch will also cover the cost of the ball machine, even if not configured to do so.
