It is always a stupid thing when there are two matches within 3 hours (in order to gain some rest).
Just fix, but I agree the costs of re-schedule matches......when it becomes so cheap (or free maybe), the opponent will almost all the time re-schedule his matches against you when it will come in handy, or to annoy you!

Just set a min. of 3 hours between matches but let the 2 tokens stand

My opinion!
