Right but if you charge a fee to cancel then you've just made the no-show problem worse. Who would voluntarily pay fee when you can just do... nothing?

That's only true if the fee is greater than the paid cost, but the fee is only 40%. That means people still get back 60% of their money.

To put it another way, they could pay a $40 fee or lose $100 by doing nothing. Most people would rather pay the fee and get their $60 back.
