When you go to manage a reservation, then Properties, then change the arrival or departure date, the "Apply Cancellation Fee" box appear, AND it is already checked. This is incredibly stupid. First, the box is completely useless since even if you were to use it to apply a cancellation fee, it doesn't add the tax. Second, why would you have it automatically checked, when more than 90% of the time there is no need to charge a cancellation fee, including 99.9% of time when you're changing the departure date. So now, when a guest requests to shorten their stay, our employee will shorten the stay and not notice that this incredibly useless box appears and then add the charge. Then the guest checks in and an employee with take the payment that Mews says is due, not realizing that the amount due includes the cancellation fee, thereby overcharging the guest. Then, because it's not taxed, it's showing up on our accounting report and then our tax owed doesn't doesn't match our sales.

If you want to have a completely useless box appear, fine. Just don't have it automatically checked, the same way that is an option for the apply cancellation fee when you cancel a reservation, which is a much more likely time that you would need that box to appear if it actually worked properly.
